|
|
- **Todo:** Remove previously deprecated mixins
|
|
- `float()`
|
|
- `form-control-mixin()`
|
|
- `retina-img()`
|
|
- `text-hide()` (also dropped the associated utility class, `.text-hide`)
|
|
- `visibility()`
|
|

|
|
- **Todo:** Rearrange forms source files (under `scss/forms/`)
|
|
- **Todo:** Rearrange grid source files (under `scss/grid/`)
|
|
- Removed print styles and `$enable-print-styles` variable. Print display classes, however, have remained intact. [See #28339](https://github.com/twbs/bootstrap/pull/28339).
|
|
|
|
## JavaScript
|
|
|
|
Changes to our source and compiled JavaScript files.
|
|
|
|
- Dropped jQuery dependency and rewrote plugins to be in regular JavaScript.
|
|
|
|
## Grid and layout
|
|
|
|
Changes to any layout tools and our grid system.
|
|
|
|
- Dropped `.media` component as it can be built with utility classes. [See #28265](https://github.com/twbs/bootstrap/pull/28265).
|
|

|
|

## Content, Reboot, etc
|

|
|
|
|
- **Todo:** Make RFS enabled by default
|
|
- Reset default horizontal `padding` on `<ul>` and `<ol>` elements from browser default `40px` to `2rem`.
|
|
|
|
## Forms
|
|
|
|
- Rearranged form documentation under its own top-level section.
|
|
- Split out old Forms page into several subpages
|
|
- Moved input groups docs under new Forms section
|
|
- Rearranged source Sass files under `scss/forms/`, including moving over input group styles.
|
|
- Combined native and custom checkboxes and radios into single `.form-check` class.
|
|
- New checks support sizing via `em`/`font-size` or explicit modifier classes now.
|
|
- Dropped `.custom-control` and associated classes.
|
|
- Combined native and custom selects into `.form-select`.
|
|
- Dropped `.custom-select` and associated classes.
|
|
- Dropped native `.form-control-file` and `.form-control-range` components.
|
|
- Renamed `.custom-file` to `.form-file` (including variables).
|
|
- Refactored `.form-file` markup to resolve some visual bugs while allowing translation and button text changes via HTML instead of CSS.
|
|
- Renamed `.custom-range` to `.form-range` (including variables).
|
|
- Dropped `.form-group` for margin utilities (we've replaced our docs examples with `.mb-3`).

|
## Components
|
|
|
|
### Alerts
|
|
|
|
- **Todo:** Remove 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.
|
|
|
|
- **Todo:** Removed and replaced `.badge` modifier classes with background utility classes (e.g., use `.bg-primary` instead of `.badge-primary`)
|
|
- **Todo:** Removed `.badge-pill` for the `.rounded-pill` utility class
|
|
- **Todo:** Removed badge's hover and focus styles for `a.badge` and `button.badge`.
|
|
|
|
### Jumbotron
|
|
|
|
- The jumbotron component is removed in favor of utility classes like `.bg-light` for the background color and `.p-*` classes to control padding.
|
|
|
|
### Popovers
|
|
|
|
- Renamed `.arrow` to `.popover-arrow`
|
|
|
|
### Tooltips
|
|
|
|
- Renamed `.arrow` to `.tooltip-arrow`
|
|
|
|
## Accessibility
|
|
|
|
- `.sr-only-focusable` does not require `.sr-only` anymore. [See #28720](https://github.com/twbs/bootstrap/pull/28720).
|
|
|
|
## Utilities
|
|
|
|
- Renamed `.text-monospace` to `.font-monospace`
|
|
- 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).
|
|
- **Todo:** Drop `.text-hide` as it's an antiquated method for hiding text that shouldn't be used anymore
|
|
- **Todo:** Split utilities into property-value utility classes and helpers
|
|
|
