— Previously we weren't including the border-width on the computed height, leading to alignment issues.
— New system utilizes three variables (not ideal, but straightforward) for computing these heights. One for the vertical border, one for the line-height/font-size/padding dance, and one to add those together.
— Updates CSS across forms and custom forms to use new sizing. Special note here: form validation icon sizing uses the inner variables because background-image doesn't bleed into borders unless explicit background-clip.
* Replace backdrop with simple noop mouse listener
As discussed in https://github.com/twbs/bootstrap/pull/22422 the current
approach of injecting a backdrop (to work around iOS' broken event
delegation for the `click` event) has annoying consequences on
touch-enabled laptop/desktop devices.
Instead of a backdrop `<div>`, here we simply add extra empty/noop
mouse listeners to the immediate children of `<body>` (and remove
them when the dropdown is closed) in order to force iOS to properly
bubble a `click` resulting from a tap (essentially, method 2 from
https://www.quirksmode.org/blog/archives/2014/02/mouse_event_bub.html)
This is sufficient (except in rare cases where the user does manage to tap
on the body itself, rather than any child elements of body - which is not
very likely in an iOS phone/tablet scenario for most layouts) to get iOS to
get a grip and do the correct event bubbling/delegation, meaning the regular
"click" event will bubble back to the `<body>` when tapping outside of the dropdown,
and the dropdown will close properly (just like it already does, even without
this fix, in non-iOS touchscreen devices/browsers, like Chrome/Android and
Windows on a touch laptop).
This approach, though a bit hacky, has no impact on the DOM structure, and
has no unforeseen side effects on touch-enabled laptops/desktops. And crucially,
it works just fine in iOS.
* Remove dropdown backdrop styles
* Update doc for dropdowns and touch-enabled devices
* Drop -x and -y as they're all the same
- Also move -width to elsewhere in the vars because it makes no sense by spacers.
- Update values of -x and -y across main Sass and docs Sass.
* Update docs to reflect changes; link to spacing utils from options page
The actual available size of the navbar toggler icon is 30px, but the
SVG uses a 32 unit grid. This commit uses a 30 unit grid and updates
icon accordingly.
- <progress> element didn't allow animation, labels overlaid, multiple bars, etc.
- Revamps CSS to use something more similar to v3's implementation
- Ditches variant mixin for `bg-` utils
- Rebuilds docs to match, including adding a new Height section for customizing that.
Only potential remaining todo is adding `.sr-only` instances to within the bar. Unsure if that's necessary.
- Overhauls the states, including the link/button variants, for list groups to better match how we handle .btn states.
- Moved the .list-group-item-action styles before the .list-group-item so that we don't have to do as much overriding.
- Removed the plain-hover-focus mixins from the disabled and active states since they're unnecessary.
- Added support for :active states on the .list-group-item-action variant (for the current click state).
- Removed the heading and text classes and variables since we can accomplish the same thing with utilities.
- Added support for :disabled on the .list-group-item-action as well since we can use those with button elements.
- Rearranged docs to reflect all the above changes.
- Reformatted some Sass variables.
- No need to set hover and focus on disabled or active elements. Disabled has no interactivity and active will inherit the focus.
- Also removes two now unused vars.
Turns out we did have the correct height calculation with our custom selects. The problem was we lacked a shared line-height with our buttons and inputs.
This restores the previous `calc` math and adds a line-height that reuses the input line-height.
This revamps the indicators to use flexbox instead of inline-block for added flexbility (hah). Indicators now automatically scale based on the number of elements present, and max out at the `$carousel-indicator-width` instead of always being that wide.
- Require inner element for the icon for improved customization (e.g., drop the element to replace it with your own icon font or SVG)
- Tighten up padding
- Better comments
* remove the $enable-flex variable option
* remove bootstrap-flex.css dist file and it's grunt task
* remove the separate flex css file for docs; it's all the same now
* remove flexbox docs (porting some to the main grid docs in next commit)
* clean up few grid docs bits to simplify copy, start to mention flexbox
* port relevant flexbox-grid.md content to grid.md
- clean up mixins
- update how it works section
- bring over sizing and alignment sections
* remove the $enable-flex from the options.md page
* update lead paragraph to mention flexbox
* update migration to mention loss of ie9 support
* remove mention of flexbox dist file
* clarify IE support
* making a note
* remove flexbox variant mentions from component docs
- updates docs for media object, navs, list group, and cards to consolidate docs
- no more need to callout flexbox variants since it's now the default
* remove $enable-flex if/else from sass files
* remove flex dist files
* update scss lint property order to account for flex properties
* linting
* change to numberless classes for autosizing, wrap in highlighting div
* bump gruntfile and postcss to ie10
* redo intro sections
* rearrange
* phew, redo hella grid docs
- rearrange all the things
- consolidate some bits
* remove reference to flexbox mode
* more border action for demo
* Make some changes to the .card's in .card-deck's to ensure footers align to the bottom
This pulls in some changes from #18462 to include a set of generic color variables. It doesn't include a Sass map for generating the theme colors yet, since we can't easily do that for all components, but does give a few more color choices to folks and an easier way to customize.
* Darken dismiss icon opacity
* Darken text on active list group items
* Darken light gray for accessibility/contrast, then update gray and dark gray to match
* make spacer utils responsive by grid tier
* update scale to add two levels, document them
* change responsive spacing utils to avoid the xs abbreviation in the class name for that tier
* update code snippet to match source
* update usage in our docs
* linter
* docs updates
