## Documentation changes
|
||||
|
||||
- Redesigned homepage, docs layout, and footer.
|
||||
- Added [new Parcel guide](https://getbootstrap.com/docs/5.0/getting-started/parcel/).
|
||||
- Added [new Customize section](https://getbootstrap.com/docs/5.0/customize/overview/), replacing [v4's Theming page](https://getbootstrap.com/docs/4.6/getting-started/theming/), with new details on Sass, global configuration options, color schemes, CSS variables, and more.
|
||||
- Reorganized all form documentation into [new Forms section](https://getbootstrap.com/docs/5.0/forms/overview/), breaking apart the content into more focused pages.
|
||||
- Similarly, updated [the Layout section](https://getbootstrap.com/docs/5.0/layout/breakpoints/), to flesh out grid content more clearly.
|
||||
- Renamed "Navs" component page to "Navs & Tabs".
|
||||
- Renamed "Checks" page to "Checks & radios".
|
||||
- Redesigned the navbar and added a new subnav to make it easier to get around our sites and docs versions.
|
||||
- Added new keyboard shortcut for the search field: <kbd>Ctrl + /</kbd>.
|
||||
|
||||
## Sass
|
||||
|
||||
- We've ditched the default Sass map merges to make it easier to remove redundant values. Keep in mind you now have to define all values in the Sass maps like `$theme-colors`. Check out how to deal with [Sass maps]({{< docsref "/customize/sass#maps-and-loops" >}}).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `color-yiq()` function and related variables to `color-contrast()` as it's no longer related to YIQ colorspace. [See #30168.](https://github.com/twbs/bootstrap/pull/30168/)
|
||||
- `$yiq-contrasted-threshold` is renamed to `$min-contrast-ratio`.
|
||||
- `$yiq-text-dark` and `$yiq-text-light` are respectively renamed to `$color-contrast-dark` and `$color-contrast-light`.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Removed print styles and `$enable-print-styles` variable. Print display classes are still around. [See #28339](https://github.com/twbs/bootstrap/pull/28339).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `color()`, `theme-color()`, and `gray()` functions in favor of variables. [See #29083](https://github.com/twbs/bootstrap/pull/29083).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `theme-color-level()` function to `color-level()` and now accepts any color you want instead of only `$theme-color` colors. [See #29083](https://github.com/twbs/bootstrap/pull/29083) **Watch out:** `color-level()` was later on dropped in `v5.0.0-alpha3`.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `$enable-prefers-reduced-motion-media-query` and `$enable-pointer-cursor-for-buttons` to `$enable-reduced-motion` and `$enable-button-pointers` for brevity.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Removed the `bg-gradient-variant()` mixin. Use the `.bg-gradient` class to add gradients to elements instead of the generated `.bg-gradient-*` classes.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> **Removed previously deprecated mixins:**
|
||||
- `hover`, `hover-focus`, `plain-hover-focus`, and `hover-focus-active`
|
||||
- `float()`
|
||||
- `form-control-mixin()`
|
||||
- `nav-divider()`
|
||||
- `retina-img()`
|
||||
- `text-hide()` (also dropped the associated utility class, `.text-hide`)
|
||||
- `visibility()`
|
||||
- `form-control-focus()`
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `scale-color()` function to `shift-color()` to avoid collision with Sass's own color scaling function.
|
||||
|
||||
- `box-shadow` mixins now allow `null` values and drop `none` from multiple arguments. [See #30394](https://github.com/twbs/bootstrap/pull/30394).
|
||||
|
||||
- The `border-radius()` mixin now has a default value.
|
||||
|
||||
## Color system
|
||||
|
||||
- The color system which worked with `color-level()` and `$theme-color-interval` was removed in favor of a new color system. All `lighten()` and `darken()` functions in our codebase are replaced by `tint-color()` and `shade-color()`. These functions will mix the color with either white or black instead of changing its lightness by a fixed amount. The `shift-color()` will either tint or shade a color depending on whether its weight parameter is positive or negative. [See #30622](https://github.com/twbs/bootstrap/pull/30622) for more details.
|
||||
|
||||
- Added new tints and shades for every color, providing nine separate colors for each base color, as new Sass variables.
|
||||
|
||||
- Improved color contrast. Bumped color contrast ratio from 3:1 to 4.5:1 and updated blue, green, cyan, and pink colors to ensure WCAG 2.1 AA contrast. Also changed our color contrast color from `$gray-900` to `$black`.
|
||||
|
||||
- To support our color system, we've added new custom `tint-color()` and `shade-color()` functions to mix our colors appropriately.
|
||||
|
||||
## Grid updates
|
||||
|
||||
- **New breakpoint!** Added new `xxl` breakpoint for `1400px` and up. No changes to all other breakpoints.
|
||||
|
||||
- **Improved gutters.** Gutters are now set in rems, and are narrower than v4 (`1.5rem`, or about `24px`, down from `30px`). This aligns our grid system's gutters with our spacing utilities.
|
||||
- Added new [gutter class](https://getbootstrap.com/docs/5.0/layout/gutters/) (`.g-*`, `.gx-*`, and `.gy-*`) to control horizontal/vertical gutters, horizontal gutters, and vertical gutters.
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `.no-gutters` to `.g-0` to match new gutter utilities.
|
||||
|
||||
- Columns no longer have `position: relative` applied, so you may have to add `.position-relative` to some elements to restore that behavior.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped several `.order-*` classes that often went unused. We now only provide `.order-1` to `.order-5` out of the box.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped the `.media` component as it can be easily replicated with utilities. [See #28265](https://github.com/twbs/bootstrap/pull/28265) and the [flex utilities page for an example]({{< docsref "/utilities/flex#media-object" >}}).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> `bootstrap-grid.css` now only applies `box-sizing: border-box` to the column instead of resetting the global box-sizing. This way, our grid styles can be used in more places without interference.
|
||||
|
||||
- `$enable-grid-classes` no longer disables the generation of container classes anymore. [See #29146.](https://github.com/twbs/bootstrap/pull/29146)
|
||||
|
||||
- Updated the `make-col` mixin to default to equal columns without a specified size.
|
||||
|
||||
## Content, Reboot, etc
|
||||
|
||||
- **[RFS]({{< docsref "/getting-started/rfs" >}}) is now enabled by default.** Headings using the `font-size()` mixin will automatically adjust their `font-size` to scale with the viewport. _This feature was previously opt-in with v4._
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Overhauled our display typography to replace our `$display-*` variables and with a `$display-font-sizes` Sass map. Also removed the individual `$display-*-weight` variables for a single `$display-font-weight` and adjusted `font-size`s.
|
||||
|
||||
- Added two new `.display-*` heading sizes, `.display-5` and `.display-6`.
|
||||
|
||||
- **Links are underlined by default** (not just on hover), unless they're part of specific components.
|
||||
|
||||
- **Redesigned tables** to refresh their styles and rebuild them with CSS variables for more control over styling.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Nested tables do not inherit styles anymore.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> `.thead-light` and `.thead-dark` are dropped in favor of the `.table-*` variant classes which can be used for all table elements (`thead`, `tbody`, `tfoot`, `tr`, `th` and `td`).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> The `table-row-variant()` mixin is renamed to `table-variant()` and accepts only 2 parameters: `$color` (colon name) and `$value` (color code). The border color and accent colors are automatically calculated based on the table factor variables.
|
||||
|
||||
- Split table cell padding variables into `-y` and `-x`.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `.pre-scrollable` class. [See #29135](https://github.com/twbs/bootstrap/pull/29135)
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> `.text-*` utilities do not add hover and focus states to links anymore. `.link-*` helper classes can be used instead. [See #29267](https://github.com/twbs/bootstrap/pull/29267)
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `.text-justify` class. [See #29793](https://github.com/twbs/bootstrap/pull/29793)
|
||||
|
||||
- Reset default horizontal `padding-left` on `<ul>` and `<ol>` elements from browser default `40px` to `2rem`.
|
||||
|
||||
- Added `$enable-smooth-scroll`, which applies `scroll-behavior: smooth` globally—except for users asking for reduced motion through `prefers-reduced-motion` media query. [See #31877](https://github.com/twbs/bootstrap/pull/31877)
|
||||
|
||||
## RTL
|
||||
|
||||
- Horizontal direction specific variables, utilities, and mixins have all been renamed to use logical properties like those found in flexbox layouts—e.g., `start` and `end` in lieu of `left` and `right`.
|
||||
|
||||
## Forms
|
||||
|
||||
- **Added new floating forms!** We've promoted the Floating labels example to fully supported form components. [See the new Floating labels page.]({{< docsref "/forms/floating-labels" >}})
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> **Consolidated native and custom form elements.** Checkboxes, radios, selects, and other inputs that had native and custom classes in v4 have been consolidated. Now nearly all our form elements are entirely custom, most without the need for custom HTML.
|
||||
- `.custom-check` is now `.form-check`.
|
||||
- `.custom-check.custom-switch` is now `.form-check.form-switch`.
|
||||
- `.custom-select` is now `.form-select`.
|
||||
- `.custom-file` and `.form-file` have been replaced by custom styles on top of `.form-control`.
|
||||
- `.custom-range` is now `.form-range`.
|
||||
- Dropped native `.form-control-file` and `.form-control-range`.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `.input-group-append` and `.input-group-prepend`. You can now just add buttons and `.input-group-text` as direct children of the input groups.
|
||||
|
||||
- The longstanding [Missing border radius on input group with validation feedback bug](https://github.com/twbs/bootstrap/issues/25110) is finally fixed by adding an additional `.has-validation` class to input groups with validation.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> **Dropped form-specific layout classes for our grid system.** Use our grid and utilities instead of `.form-group`, `.form-row`, or `.form-inline`.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Form labels now require `.form-label`.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> `.form-text` no longer sets `display`, allowing you to create inline or block help text as you wish just by changing the HTML element.
|
||||
|
||||
- Validation icons are no longer applied to `<select>`s with `multiple`.
|
||||
|
||||
### JavaScript
|
||||
- Rearranged source Sass files under `scss/forms/`, including input group styles.
|
||||
|
||||
<hr class="my-5">
|
||||
|
||||
## Components
|
||||
|
||||
- Unified `padding` values for alerts, breadcrumbs, cards, dropdowns, list groups, modals, popovers, and tooltips to be based on our `$spacer` variable. [See #30564](https://github.com/twbs/bootstrap/pull/30564).
|
||||
|
||||
### Accordion
|
||||
|
||||
- Added [new accordion component]({{< docsref "/components/accordion" >}}!
|
||||
|
||||
### Alerts
|
||||
|
||||
- Alerts now have [examples with icons]({{< docsref "/components/alerts#icons" >}}).
|
||||
|
||||
- Removed custom styles for `<hr>`s in each alert since they already use `currentColor`.
|
||||
|
||||
### Badges
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped all `.badge-*` color classes for background utilities (e.g., use `.bg-primary` instead of `.badge-primary`).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `.badge-pill`—use the `.rounded-pill` utility instead.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Removed hover and focus styles for `<a>` and `<button>` elements.
|
||||
|
||||
- Increased default padding for badges from `.25em`/`.5em` to `.35em`/`.65em`.
|
||||
|
||||
### Breadcrumbs
|
||||
|
||||
- Simplified the default appearance of breadcrumbs by removing `padding`, `background-color`, and `border-radius`.
|
||||
|
||||
- Added new CSS custom property `--bs-breadcrumb-divider` for easy customization without needing to recompile CSS.
|
||||
|
||||
### Buttons
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> **[Toggle buttons](http://getbootstrap.com/docs/5.0/forms/checks-radios/#toggle-buttons), with checkboxes or radios, no longer require JavaScript and have new markup.** We no long require a wrapping element, add `.btn-check` to the `<input>`, and pair it with any `.btn` classes on the `<label>`. [See #30650](https://github.com/twbs/bootstrap/pull/30650). _The docs for this has moved from our Buttons page to the new Forms section._
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> **Dropped `.btn-block` for utilities.** Instead of using `.btn-block` on the `.btn`, wrap your buttons with `.d-grid` and a `.gap-*` utility to space them as needed. Switch to responsive classes for even more control over them. [Read the docs for some examples.](http://getbootstrap.com/docs/5.0/components/buttons/#block-buttons)
|
||||
|
||||
- Updated our `button-variant()` and `button-outline-variant()` mixins to support additional parameters.
|
||||
|
||||
- Updated buttons to ensure increased contrast on hover and active states.
|
||||
|
||||
- Disabled buttons now have `pointer-events: none;`.
|
||||
|
||||
### Card
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `.card-deck` in favor of our grid. Wrap your cards in column classes and add a parent `.row-cols-*` container to recreate card decks (but with more control over responsive alignment).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `.card-columns` in favor of Masonry. [See #28922](https://github.com/twbs/bootstrap/pull/28922).
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Replaced the `.card` based accordion with a [new Accordion component]({{< docsref "/components/accordion" >}}).
|
||||
|
||||
### Carousel
|
||||
|
||||
- Added new [`.carousel-dark` variant]({{< docsref "/components/carousel#dark-variant" >}}) for dark text, controls, and indicators (great for lighter backgrounds).
|
||||
|
||||
- Replaced chevron icons for carousel controls with new SVGs from [Bootstrap Icons]({{< param "icons" >}}).
|
||||
|
||||
### Close buttton
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `.close` to `.btn-close` for a less generic name.
|
||||
|
||||
- Close buttons now use a `background-image` (embedded SVG) instead of a `×` in the HTML, allowing for easier customization without the need to touch your markup.
|
||||
|
||||
- Added new `.btn-close-white` variant that uses `filter: invert(1)` to enable higher contrast dismiss icons against darker backgrounds.
|
||||
|
||||
### Collapse
|
||||
|
||||
- Removed scroll anchoring for accordions.
|
||||
|
||||
### Dropdowns
|
||||
|
||||
- Added new `.dropdown-menu-dark` variant and associated variables for on-demand dark dropdowns.
|
||||
|
||||
- Added new variable for `$dropdown-padding-x`.
|
||||
|
||||
- Darkened the dropdown divider for improved contrast.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> All the events for the dropdown are now triggered on the dropdown toggle button and then bubbled up to the parent element.
|
||||
|
||||
- Dropdown menus now have a `data-bs-popper="static"` attribute set when the positioning of the dropdown is static and `data-bs-popper="none"` when dropdown is in the navbar. This is added by our JavaScript and helps us use custom position styles without interfering with Popper's positioning.
|
||||
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped `flip` option for dropdown plugin in favor of native Popper configuration. You can now disable the flipping behavior by passing an empty array for [`fallbackPlacements`](https://popper.js.org/docs/v2/modifiers/flip/#fallbackplacements) option in [flip](https://popper.js.org/docs/v2/modifiers/flip/) modifier.
|
||||
|
||||
- Dropdown menus can now be clickable with a new `autoClose` option to handle the [auto close behavior]({{< docsref "/components/dropdowns#auto-close-behavior" >}}). You can use this option to accept the click inside or outside the dropdown menu to make it interactive.
|
||||
|
||||
- Dropdowns now support `.dropdown-item`s wrapped in `<li>`s.
|
||||
- Fixed offcanvas focus issues when scrolling is allowed.
|
||||
- Fixed click handling on tabs.
|
||||
|
||||
### Sass
|
||||
### Jumbotron
|
||||
|
||||
- Added new `color-scheme` mixin
|
||||
- Update the `make-col` mixin to default to equal widths without a specified size
|
||||
- <span class="badge bg-danger">Breaking</span> Dropped the jumbotron component as it can be replicated with utilities. [See our new Jumbotron example for a demo.](https://getbootstrap.com/docs/5.0/examples/jumbotron/)
|
||||
|
||||
## v5.0.0-beta3
|
||||
|
||||
### Components
|
||||
### List group
|
||||
|
||||
- Added new [`.list-group-numbered` modifier]({{< docsref "/components/list-group#numbered" >}}) to list groups.
|
||||
|
||||
### JavaScript
|
||||
### Navs and tabs
|
||||
|
||||
- All plugins can now accept a CSS selector as the first argument. You can either pass a DOM element or any valid CSS selector to create a new instance of the plugin:
|
||||
- Added new `null` variables for `font-size`, `font-weight`, `color`, and `:hover` `color` to the `.nav-link` class.
|
||||
|
||||
```js
|
||||
var modal = new bootstrap.Modal('#myModal')
|
||||
var dropdown = new bootstrap.Dropdown('[data-bs-toggle="dropdown"]')
|
||||
```
|
||||
### Navbars
|
||||
|
||||
- Dropped `flip` option for dropdown plugin in favor of native popper configuration. You can now disable the flipping behavior by passing an empty array for [`fallbackPlacements`](https://popper.js.org/docs/v2/modifiers/flip/#fallbackplacements) option in [flip](https://popper.js.org/docs/v2/modifiers/flip/) modifier.
|
||||
- <span class="badge bg-danger">Breaking</span> Navbars now require a container within (to drastically simplify spacing requirements and CSS required).
|
||||
|
||||
### Utilities
|
||||
### Offcanvas
|
||||
|
||||
- Dropped the `0` entry in `$border-widths` map to remove the duplicated `.border-0` class.
|
||||
- Added the new [offcanvas component]({{< docsref "/components/offcanvas" >}}).
|
||||
|
||||
## v5.0.0-beta2
|
||||
### Pagination
|
||||
|
||||
### Utilities
|
||||
- Pagination links now have customizable `margin-left` that are dynamically rounded on all corners when separated from one another.
|
||||
|
||||
- Renamed `--aspect-ratio` to `--bs-aspect-ratio` to be consistent with other custom properties.
|
||||
- Extended the `.visually-hidden-focusable` helper to also work on containers, using `:focus-within`.
|
||||
- `bootstrap-utilities.css` now also includes our helpers. Helpers don't need to be imported in custom builds anymore.
|
||||
- Extended form validation states customization capabilities. Added three new optional parameters to the `form-validation-state` mixin: `tooltip-color`, `tooltip-bg-color`, `focus-box-shadow`. These parameters can be set in the `$form-validation-states` map. [See #31757](https://github.com/twbs/bootstrap/pull/31757).
|
||||
- Added `transition`s to pagination links.
|
||||
|
||||
### JavaScript
|
||||
### Popovers
|
||||
|
||||
- Restored `offset` option for Dropdown, Popover and Tooltip plugins.
|
||||
- The default value for the `fallbackPlacements` is changed to `['top', 'right', 'bottom', 'left']` for better placement of popper elements.
|
||||
- All the events for the dropdown are now triggered on the dropdown toggle button and then bubbled up to the parent element.
|
||||
- Dropdown menus now have a `data-bs-popper="static"` attribute set when the positioning of the dropdown is static and `data-bs-popper="none"` when dropdown is in the navbar. This is added by our JavaScript and helps us use custom position styles without interfering with Popper's positioning.
|
||||
- `popperConfig` can be passed as a function that accepts the Bootstrap's default Popper config as an argument, so that you can merge this default configuration in your way.
|
||||

|
||||
|
||||

### RTL
|
||||
### Spinners

||||
#### Sass
|
||||
- Improved spinner vertical alignment.
|
||||
|
||||
Horizontal direction sensitive variables, utilities and mixins are renamed with more logical names — `start` and `end` in lieu of `left` and `right`.
|
||||
### Toasts
|
||||
|
||||
##### Components
|
||||
- Toasts can now be [positioned]({{< docsref "/components/toasts#placement" >}}) in a `.toast-container` with the help of [positioning utilities]({{< docsref "/utilities/position" >}}).

||||
|
||||
- Renamed `.dropleft` and `.dropright` to `.dropstart` and `.dropend`.

|
||||
|
||||
## Utilities

||||
- Renamed `.float-left` and `.float-right` to `.float-start` and `.float-end`.

|
||||
- <span class="badge bg-danger">Breaking</span> Disabled negative margins by default.
|
||||
|
||||
**Note**: if you used v4 to make RTL pages, ensure to reverse changes mentioned above: e.g. use `.*-start` where you used `.*-right`.
|
||||
- Added new `.bg-body` class for quickly setting the `<body>`'s background to additional elements.
|
||||
|
||||
##### Mixins
|
||||
|
||||
- Renamed `border-left-radius()` and `border-right-radius()` to `border-start-radius()` and `border-end-radius()` — as well as their corner relative variants (eg. `.border-bottom-left-radius` became `.border-bottom-start-radius`).
|
||||
- Renamed `caret-left()` and `caret-right()` to `caret-start()` and `caret-end()` — subsequently, the `caret()` mixin now takes `start` and `end` as arguments instead of `left` and `right`.

|
||||
|
||||
### JavaScript
|
||||
|
||||
- Data attributes for all JavaScript plugins are now namespaced to help distinguish Bootstrap functionality from third parties and your own code. For example, we use `data-bs-toggle` instead of `data-toggle`.
|
||||
- Updated Popper to v2.x:
|
||||
- Removed `offset` option from our Tooltip/Popover and Dropdown plugins; this can still be achieved using the `popperConfig` parameter.
|
||||
- The `fallbackPlacement` option has become `fallbackPlacements`.
|
||||
|
||||
### Sass
|
||||
|
||||
- Renamed `scale-color()` function to `shift-color()` to avoid collision with Sass's own color scaling function.
|
||||
|
||||
### Utilities
|
||||
- Added new [position utilities]({{< docsref "/utilities/position#arrange-elements" >}}) for `top`, `right`, `bottom`, and `left`. Values include `0`, `50%`, and `100%` for each property.

|
||||
|
||||
#### Breadcrumbs
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `.text-monospace` to `.font-monospace`.
|
||||
|
||||
- Simplified the default appearance of breadcrumbs by removing `padding`, `background-color`, and `border-radius`.

|
||||
- <span class="badge bg-danger">Breaking</span> Removed `.text-hide` as it's an antiquated method for hiding text that shouldn't be used anymore.
|
||||
|
||||
#### Toasts
|
||||
|
||||
- Toasts can now be [positioned]({{< docsref "/components/toasts#placement" >}}) in a `.toast-container` with the help of [positioning utilities]({{< docsref "/utilities/position" >}}).

|
||||
## v5.0.0-alpha3
|
||||
|
||||
### Browser support
|
||||
|
||||
- Dropped support for Microsoft Edge Legacy. See [here](#browser-support-1) for the previous browser support changes.
|
||||
|
||||
### Sass
|
||||
|
||||
- The color system which worked with `color-level()` and `$theme-color-interval` was removed in favor of a new color system. All `lighten()` and `darken()` functions in our codebase are replaced by `tint-color()` and `shade-color()`. These functions will mix the color with either white or black instead of changing its lightness by a fixed amount. The `scale-color()` (changed to `shift-color()` in Beta 1) will either tint or shade a color depending on whether its weight parameter is positive or negative. [See #30622](https://github.com/twbs/bootstrap/pull/30622) for more details.
|
||||
- Spinners now honor `prefers-reduced-motion: reduce` by slowing down animations. [See #31882](https://github.com/twbs/bootstrap/pull/31882).
|
||||
|
||||
### Reboot
|
||||
|
||||
- Introduce `$enable-smooth-scroll`, which applies `scroll-behavior: smooth` globally—except for users asking for reduced motion through `prefers-reduced-motion` media query. [See #31877](https://github.com/twbs/bootstrap/pull/31877)
|
||||
|
||||
### Buttons
|
||||
|
||||
- [Dropped `.btn-block` in favor of CSS grid utility classes.]({{< docsref "/components/buttons#block-buttons" >}}) Instead of applying `.btn-block` to individual buttons, a group of buttons now get wrapped in a parent `.d-grid` class and can use `.gap-*` utilities for spacing. For individual "block buttons", add `.w-100`.
|
||||
|
||||
### Forms
|
||||
|
||||
- The longstanding [Missing border radius on input group with validation feedback bug](https://github.com/twbs/bootstrap/issues/25110) is finally fixed by adding an additional `.has-validation` class to input groups with validation.
|
||||
- Promoted the Floating labels example to fully supported form component. [See the new Floating labels page.]({{< docsref "/forms/floating-labels" >}})
|
||||
- File inputs now use the `.form-control` class and don't require JavaScript, additional HTML, or additional classes. [See #31955](https://github.com/twbs/bootstrap/pull/31955).
|
||||
- Added `cursor:pointer` to `.form-control-color` color inputs.
|
||||
|
||||
### Utilities
|
||||
|
||||
- **Text utilities:**
|
||||
- Added `.fs-*` utilities for `font-size` utilities (with RFS enabled). These use the same scale as HTML's default headings (1-6, large to small), and can be modified via Sass map.
|
||||
- Renamed `.font-weight-*` utilities as `.fw-*` for brevity and consistency.
|
||||
- Renamed `.font-style-*` utilities as `.fst-*` for brevity and consistency.
|
||||
- Added `.d-grid` to display utilities
|
||||
- Added new `gap` utilities (`.gap`) for CSS Grid layouts
|
||||
- Removed `.rounded-sm` and `rounded-lg`, and introduced `.rounded-0` to `.rounded-3`. [See #31687](https://github.com/twbs/bootstrap/pull/31687).
|
||||
|
||||
## v5.0.0-alpha2
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `.font-weight-*` utilities as `.fw-*` for brevity and consistency.
|
||||
|
||||
### Sass
|
||||
- <span class="badge bg-danger">Breaking</span> Renamed `.font-style-*` utilities as `.fst-*` for brevity and consistency.
|
||||
|
||||
- Added default parameters to each `border-radius` mixin. [See #31571](https://github.com/twbs/bootstrap/pull/31571).
|
||||
- Updated the next breakpoint when targeting only the `xs` breakpoint. [See #31500](https://github.com/twbs/bootstrap/pull/31500).
|
||||
- `box-shadow` mixins now allow `null` values and drop `none` from multiple arguments. [See #30394](https://github.com/twbs/bootstrap/pull/30394).
|
||||
- Added `.d-grid` to display utilities and new `gap` utilities (`.gap`) for CSS Grid and flexbox layouts.
|
||||
|
||||
### Docs
|
||||
- <span class="badge bg-danger">Breaking</span> Removed `.rounded-sm` and `rounded-lg`, and introduced a new scale of classes, `.rounded-0` to `.rounded-3`. [See #31687](https://github.com/twbs/bootstrap/pull/31687).

|
||||
|
||||
### Layout
|
||||
- Moved the `.d-none` utility in our CSS to give it more weight over other display utilities.
|
||||
|
||||
- Container horizontal padding updated to match the gutter size of `.row`s.
|
||||
- [#31439](https://github.com/twbs/bootstrap/pull/31439): Removed `flex: 1 0 100%` from rows due to regressions in grid behavior.

||||
|
||||
### Reboot

|
||||
- Improved `$cyan` (and its theme alias `$info`) color to be more vibrant (moving from `#17a2b8` to `#0dcaf0`).
|
||||
|
||||
### Forms
|
||||
|
||||
- [#31383](https://github.com/twbs/bootstrap/pull/31383): Resized checks and radios to be `1em` instead of `1.25em` in an effort to make them scale better with custom `$font-size-base` values and more.

||||
|
||||
#### Badges
|
||||
|
||||

||||
#### Close button
|
||||
|
||||
- Renamed `.close` to `.btn-close` for a less generic name.
|
||||

|
||||
- Added new variables to better control the customization.
|

|
||||
- We've dropped the `.embed-responsive-item` and element group selector in favor of a simpler `.ratio > *` selector. No more class is needed, and the ratio helper now works with any HTML element.
|
||||

||||
|
||||
---
|
||||
- **Dropped jQuery dependency** and rewrote plugins to be in regular JavaScript.
|
||||
|
||||
## v5.0.0-alpha1
|
||||
- <span class="badge bg-danger">Breaking</span> Data attributes for all JavaScript plugins are now namespaced to help distinguish Bootstrap functionality from third parties and your own code. For example, we use `data-bs-toggle` instead of `data-toggle`.

||||
### Browser support
|
||||
- **All plugins can now accept a CSS selector as the first argument.** You can either pass a DOM element or any valid CSS selector to create a new instance of the plugin:
|
||||
|
||||
See the browser and devices page for details on what is currently supported in Bootstrap 5. Since v4, here's what's changed to our browser support:
|
||||
```js
|
||||
var modal = new bootstrap.Modal('#myModal')
|
||||
var dropdown = new bootstrap.Dropdown('[data-bs-toggle="dropdown"]')

|
||||
|
||||
### Sass
|
||||
- The default value for the `fallbackPlacements` is changed to `['top', 'right', 'bottom', 'left']` for better placement of Popper elements. **Applies to dropdowns, popovers, and tooltips.**
|
||||
|
||||
Changes to our source Sass files and compiled CSS.
|
||||
|
||||
- Removed `hover`, `hover-focus`, `plain-hover-focus`, and `hover-focus-active` mixins. Use regular CSS syntax for these moving forward. [See #28267](https://github.com/twbs/bootstrap/pull/28267).

|
||||
- The `theme-color-level()` function is renamed to `color-level()` and now accepts any color you want instead of only `$theme-color` colors. [See #29083](https://github.com/twbs/bootstrap/pull/29083) **Watch out:** `color-level()` was later on dropped in `v5.0.0-alpha3`.
|
||||
- `$enable-grid-classes` doesn't disable the generation of container classes anymore [See #29146](https://github.com/twbs/bootstrap/pull/29146)
|
||||
- Renamed `$enable-prefers-reduced-motion-media-query` and `$enable-pointer-cursor-for-buttons` to `$enable-reduced-motion` and `$enable-button-pointers` for brevity.
|

- Line heights are dropped from several components to simplify our codebase. The `button-size()` and `pagination-size()` do not accept line height parameters anymore. [See #29271](https://github.com/twbs/bootstrap/pull/29271)
|
||||
- The `button-variant()` mixin now accepts 3 optional color parameters, for each button state, to override the color provided by `color-contrast()`. By default, these parameters will find which color provides more contrast against the button state's background color with `color-contrast()`.
|
||||
- The `button-outline-variant()` mixin now accepts an additional argument, `$active-color`, for setting the button's active state text color. By default, this parameter will find which color provides more contrast against the button's active background color with `color-contrast()`.
|
||||
- Ditch the Sass map merges, which makes it easier to remove redundant values. Keep in mind you now have to define all values in the Sass maps like `$theme-colors`. Check out how to deal with [Sass maps]({{< docsref "/customize/sass#maps-and-loops" >}}).
|
||||
- `color-yiq()` function and related variables are renamed to `color-contrast()` since it's not related to YIQ colorspace anymore. [See #30168.](https://github.com/twbs/bootstrap/pull/30168/)
|
||||
- `$yiq-contrasted-threshold` is renamed to `$min-contrast-ratio`.
|
||||
- `$yiq-text-dark` and `$yiq-text-light` are respectively renamed to `$color-contrast-dark` and `$color-contrast-light`.
|
||||
- Linear gradients are simplified when gradients are enabled and therefore, `gradient-bg()` now only accepts an optional `$color` parameter.
|
||||
- The `bg-gradient-variant()` mixin is removed since the `.bg-gradient` class can now be used to add gradients to elements instead of the `.bg-gradient-*` classes.
|
||||
- The `media-breakpoint-down()` uses the breakpoint itself instead of the next breakpoint. Use `media-breakpoint-down(lg)` instead of `media-breakpoint-down(md)` to target viewports smaller than the `lg` breakpoint.
|
||||
- The `media-breakpoint-between()` mixin's second parameter also uses the breakpoint itself instead of the next breakpoint. Use `media-between(sm, lg)` instead of `media-breakpoint-between(sm, md)` to target viewports between the `sm` and `lg` breakpoints.
|
||||
- The `box-shadow()` mixin now better supports `none` and `null` with multiple arguments. Now you can pass multiple arguments with either value and get the expected output. [See #30394](https://github.com/twbs/bootstrap/pull/30394).
|
||||
- Each `border-radius()` mixin now has a default value. You can now call these mixins without specifying a border radius value and the `$border-radius` variable will be used. [See #31571](https://github.com/twbs/bootstrap/pull/31571)
|
||||
|
||||
### JavaScript
|
||||
|
||||
Changes to our source and compiled JavaScript files.
|
||||
|
||||
- Dropped jQuery dependency and rewrote plugins to be in regular JavaScript.
|
||||
- Removed underscore from public static methods like `_getInstance()` → `getInstance()`.
|
||||
|
||||
### Color system
|
||||
|
||||
We've updated the color system that powers Bootstrap to improve color contrast and provide a much more extensive set of colors.
|
||||
|
||||
- Updated blue and pink base colors (`-500`) to ensure WCAG 2.1 AA contrast.
|
||||
- Added new tints and shades for every color, providing nine separate colors for each base color, as new Sass variables.
|
||||
- To support our color system, we've added new custom `tint-color()` and `shade-color()` functions to mix our colors appropriately.
|
||||
|
||||
### Grid and layout
|
||||
|
||||
Changes to any layout tools and our grid system.
|
||||
|
||||
- Dropped the `.media` component as it can be built with utility classes. [See #28265](https://github.com/twbs/bootstrap/pull/28265) and the [flex utilities page for an example]({{< docsref "/utilities/flex#media-object" >}}).
|
||||
- Remove `position: relative` from grid columns.
|
||||
- The horizontal padding is added to the direct children in a row instead of the columns themselves.
|
||||
- This simplifies our codebase.
|
||||
- The column classes can now be used stand-alone. Whenever they are used outside a `.row`, horizontal padding won't be added.
|
||||
- The responsive gutter classes can be used to control the gutter width in horizontal, vertical or both directions.
|
||||
- The gutter width is now set in `rem` and decreased from `30px` to `1.5rem` (24px).
|
||||
- `bootstrap-grid.css` now only applies `box-sizing: border-box` to the column instead of resetting the global box-sizing. This way the grid system can be used, even if `box-sizing: border-box` is not applied to each element.
|
||||
- Removed `.no-gutters` in favor of new gutter spacing classes. Use `.g-0` instead. [Read the gutter docs for more details.]({{< docsref "/layout/gutters" >}})
|
||||
|
||||
### Content, Reboot, etc
|
||||
|
||||
Changes to Reboot, typography, tables, and more.
|
||||
|
||||
- [RFS]({{< docsref "/getting-started/rfs" >}}) enabled for automated font size rescaling. [See #29152](https://github.com/twbs/bootstrap/pull/29152)
|
||||
- Reset default horizontal `padding-left` on `<ul>` and `<ol>` elements from browser default `40px` to `2rem`.
|
||||
- Simplified table styles (no more odd top border) and tightened cell padding.
|
||||
- Nested tables do not inherit styles anymore.
|
||||
- `.thead-light` and `.thead-dark` are dropped in favor of the `.table-*` variant classes which can be used for all table elements (`thead`, `tbody`, `tfoot`, `tr`, `th` and `td`).
|
||||
- The `table-row-variant()` mixin is renamed to `table-variant()` and accepts only 2 parameters: `$color` (colon name) and `$value` (color code). The border color and accent colors are automatically calculated based on the table factor variables.
|
||||
- Split table cell padding variables into `-y` and `-x`.
|
||||
- Dropped `.pre-scrollable` class. [See #29135](https://github.com/twbs/bootstrap/pull/29135)
|
||||
- `.text-*` utilities do not add hover and focus states to links anymore. `.link-*` helper classes can be used instead. [See #29267](https://github.com/twbs/bootstrap/pull/29267)
|
||||
- Drop `.text-justify` class. [See #29793](https://github.com/twbs/bootstrap/pull/29793)
|
||||
|
||||
### Typography
|
||||
|
||||
- Removed `$display-*` variables for a new `$display-font-sizes` Sass map.
|
||||
- Removed individual `$display-*-weight` variables for a single `$display-font-weight`.
|
||||
- Added two new `.display-*` heading styles, `.display-5` and `.display-6`.
|
||||
- Resized existing display headings for a slightly more consistent set of `font-size`s.
|
||||
- Links are underlined by default (not just on hover), unless they're part of specific components.
|
||||
|
||||
### Forms
|
||||
|
||||
- Rearranged form documentation under its own top-level section.
|
||||
- Split out old Forms page into several subpages
|
||||
- Moved input groups docs under the new Forms section
|
||||
- Rearranged source Sass files under `scss/forms/`, including moving over input group styles.
|
||||
- Combined native and custom checkboxes and radios into a single `.form-check` class.
|
||||
- New checks support sizing via `em`/`font-size` or explicit modifier classes now.
|
||||
- New checks now appear larger by default for improved usability.
|
||||
- Dropped `.custom-control` and associated classes.
|
||||
- Renamed most `$custom-control` variables to `$form-control` ones.
|
||||
- Combined native and custom selects into `.form-select`.
|
||||
- Dropped `.custom-select` and associated classes.
|
||||
- Renamed most `$custom-select` variables to `$form-select` ones.
|
||||
- Updated file input component with the same overall design, but improved HTML.
|
||||
- Refactored `.form-file` markup to resolve some visual bugs while allowing translation and button text changes via HTML instead of CSS.
|
||||
- Dropped native `.form-control-file` and `.form-control-range` components entirely.
|
||||
- Renamed `.custom-file` to `.form-file` (including variables). **Watch out:** `.form-file` was later on dropped in `v5.0.0-alpha3`, now you can use `.form-control`.
|
||||
- Added support for `:focus` and `:disabled` styles.
|
||||
- Renamed `.custom-range` to `.form-range` (including variables).
|
||||
- Dropped `.form-group` for margin utilities (we've replaced our docs examples with `.mb-3`).
|
||||
- Dropped `.form-row` for the more flexible grid gutters.
|
||||
- Dropped `.form-inline` for the more flexible grid.
|
||||
- Dropped support for `.form-control-plaintext` inside `.input-group`s.
|
||||
- Dropped `.input-group-append` and `.input-group-prepend`. You can now just add buttons and `.input-group-text` as direct children of the input groups.
|
||||
- Form labels now require the `.form-label` class. Sass variables are now available to style form labels to your needs. [See #30476](https://github.com/twbs/bootstrap/pull/30476)
|
||||
- `.form-text` no longer sets `display`, but does set `color` and `font-size`. So instead of `<small class="form-text text-muted">` you should now use `<div class="form-text">`.
|
||||
|
||||
### Components
|
||||
|
||||
- Unified `padding` values for alerts, breadcrumbs, cards, dropdowns, list groups, modals, popovers, and tooltips to be based on our `$spacer` variable. [See #30564](https://github.com/twbs/bootstrap/pull/30564).
|
||||
|
||||
#### Disabled states
|
||||
|
||||
- Disabled states of the buttons, close button, pagination link & form range now have `pointer-events: none` added. This simplifies our codebase and makes it easier to override active states in CSS. [#29296](https://github.com/twbs/bootstrap/pull/29296).
|
||||
|
||||
#### Alerts
|
||||
|
||||
- Removed auto-darkening of `<hr>` elements in `.alert-*` class variants. `<hr>`s use `rgba()` for their color, so these should naturally blend anyway.
|
||||
|
||||
#### Badges
|
||||
|
||||
Badges were overhauled to better differentiate themselves from buttons and to better utilize utility classes.
|
||||
|
||||
- Removed and replaced `.badge` modifier classes with background utility classes (e.g., use `.bg-primary` instead of `.badge-primary`)
|
||||
- Removed `.badge-pill` for the `.rounded-pill` utility class
|
||||
- Removed badge's hover and focus styles for `a.badge` and `button.badge`.
|
||||
|
||||
#### Buttons
|
||||
|
||||
- The checkbox/radio toggle is removed from the button plugin in favor of a CSS only solution, which is documented in the [form checks and radios]({{< docsref "/forms/checks-radios#toggle-buttons" >}}) docs. The `.btn-check` class can be added to inputs, any label with `.btn` and modifier class can be used to theme the labels. [See #30650](https://github.com/twbs/bootstrap/pull/30650).
|
||||
|
||||
#### Cards
|
||||
|
||||
- Removed the card columns in favor of a Masonry grid [See #28922](https://github.com/twbs/bootstrap/pull/28922).
|
||||
- Removed card decks in favor of the grid which adds more flexibility over responsive behavior.
|
||||
|
||||
#### Jumbotron
|
||||
|
||||
- The jumbotron component is removed in favor of utility classes like `.bg-light` for the background color and `.p-*` classes to control padding.
|
||||
|
||||
#### Navbars
|
||||
|
||||
- All navbars now require a container within. This drastically simplifies spacing requirements and removes the need for extensive CSS overrides we added for responsive containers in v4.
|
||||
|
||||
#### Pagination
|
||||
|
||||
- Pagination links now have customizable `margin-left` that are dynamically rounded on all corners when separated from one another.
|
||||
|
||||
#### Popovers
|
||||
|
||||
- Renamed `.arrow` to `.popover-arrow`
|
||||
|
||||
#### Tooltips
|
||||
|
||||
- Renamed `.arrow` to `.tooltip-arrow`
|
||||
|
||||
### Accessibility
|
||||
|
||||
- Unlike the old `.sr-only-focusable`, which only worked in combination with `.sr-only`, `.sr-only-focusable` can be used as a standalone class without `.sr-only`. [See #28720](https://github.com/twbs/bootstrap/pull/28720).
|
||||
|
||||
### Utilities
|
||||
|
||||
### Grid
|
||||
|
||||
- Decreased the number of responsive order utilities per breakpoint. The highest order utility with a number now is `.order-5` instead of `.order-12`. [See #28874](https://github.com/twbs/bootstrap/pull/28874).
|
||||
|
||||
### Misc
|
||||
|
||||
- Added `.bg-body` for quickly setting the `<body>`'s background to additional elements.
|
||||
- Negative margin utilities are disabled by default. You can re-enable them by setting `$enable-negative-margins: true`, but keep in mind this can increase the file size quite a lot.
|
||||
|
||||
### Docs
|
||||
|
||||
- Removed "Wall of browser bugs" page because it has become obsolete
|
||||
- Switched from Jekyll to Hugo
|
||||
|
||||
### Build tools
|
||||
|
||||
- Updated all devDependencies
|
||||
- We support only the latest Node.js LTS releases which are 10 and 12 at the time of writing
