Part of an update to align the naming schemes across our components.
- Renames .popover-title to .popover-header
- Renames .popover-content to .popover-body
Refs: #22092
Responsive automatic column resets weren't working because they inherited their `max-width` from lower grid tiers. This was because we were resetting the `width`, not the `max-width`.
The premise for #22376 was that if we removed the `max-width` and `flex` properties, we could use the column classes as `width` utilities. The problem that I didn't remember at the time is that column classes have horizontal `padding` on them. This doesn't work for setting `width`. Perhaps more importantly, this causes #22649—the automatic sizing of columns is broken with the absence of `flex` styles.

— 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
- add .col-*-auto to the extend in our grid framework mixins so it gets padding
- this means we can avoid the col-12 classes in our docs for the responsive variants
instead of flex column, use wrap and an explicit flexbox break with flex-basis 100% on the navbar-collapse.
add some additional container styles for enabling flex behavior when content isn't immediate child of .navbar
- Justified and fill nav variants need .nav-item classes on the anchors in addition to .nav-link
- Fix broken styles for the .nav-justified class which wasn't actually doing what we needed it to
- revert back to display block for list items to prevent unwanted behaviors
- fixes a handful of other linked issues (see main thread)
- updates docs to include more utilities for the one example
* Fixed some linting issues
* Run npm tasks after scss cleanup
* Revert "Run npm tasks after scss cleanup"
This reverts commit 1103a0da68.

— Moves print display utils to display utils file
— Removes all other .hidden- utils
— Expands on .invisible and it's mixin to provide options for visibility: visible and visibility: hidden
* 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.

* Building on previous commit, do the same thing for figure, figcaption, and main
* Remove IE9- display from Normalize given our browser support
* Drop IE8 figure margin because we're IE10+
* No need for the h1 overrides because we reset these font and margin styles anyway in _type.scss already

* Improve comments, move table background reset to .table class instead of in reboot
* trailing space
* Make container in navbar to occupy full width even on smallest breakpoint
* Fix typo in comment
* Apply fix only on smaller breakpoint
* drop the comment as chrome doesn't have a bug here
* remove obvi comments
* proper fix for #21801
- ensures .progress-bar text is vertically centered should the height of the .progress-bar change by matching the line-height and height values
- we can't use flexbox here because the inner text of an element doesn't count as a flex item
* fix segmented buttons
changed flex-direction to row
centering is now done by align-items instead of justify-content
this way there is no need for flex property on the .btn inside .btn-group
* Update _input-group.scss
Tried redoing this in flexbox, but it falls apart really quickly. Any changes in height of the cells throws it all off since the rows become columns (and thus, content across columns cannot be equally sized). Rather than implement something with such glaring flaws, I'm nuking it outright.
- Renames .pos-f-t to .fixed-top, adds .fixed-bottom and .sticky-top
- Updates utilities Sass to be split across more files (one for position, sizing, and spacing)
- <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.
- since we're column to start, need to set row.
- note that flex-direction cannot be inherited, so we have to set it twice.
- apply the horizontal padding again to .nav-link.
- remove the .nav-item styles (un-needed).
- remove previous .nav-link styles as they were un-nested and potentially problematic in old placement should someone mix more navs in here.
since we're no longer using the .nav as a base class, we need to bring over some base styles for redoing browser list styles and setting flex in motion.
also brings with it some .nav-link styling. we're still using this global class, but with this small modification for alignment of content in responsive modes.
- 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.
- Removes the plain-hover-focus mixin from active and disabled states; no need for them.
- Adds :active and :disabled since we can use button elements here, too.
- Wrap the disabled background-image override in an -gradients condition.
- 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.
- removes original outline removal (hah)
- replaces it with an explicit `outline: 0` on `.btn`
- instead of replicating `:hover` for `:focus`, uses custom and themed `box-shadow` for an "outline"
- not mapped to the `$enable-shadows` variable because accessibility
Trying to simplify our output here by revamping these selectors. We overcomplicated things by setting hover styles for nearly every state (disabled and active included), and we set them in the wrong order.
This commit does the following:
- Reorders states so disabled comes before active, thereby removing the need to set disabled-active styles.
- Removes all focus and hover styles from disabled states as those will naturally inherit from the default button state.
- Renamed `.open` to `.show` to fix dropdown toggle highlighting.
- Tweaked some indendation in the Sass.
