Refs #19990
Continues the degruntification process.
Also removes mq4-hover-shim for now,
since it doesn't yet implement the standard PostCSS plugin interface.
Here we're doing some margin swapping, so it looks a little funky. All this does is match the margin implementation and rendering across our table and flex versions of card decks.
- Remove background-color from header and footer in inverse cards (fixes#19841)
- Update border override for header and footer in cards; only need to declare a new color
- Update the selector for targetting blockquote footers in cards
- Remove the box-shadow and switch back to border to match .card basics
- Update the header nav margin override--since we restored the border, we need that default negative margin at the bottom
- Really we didn't need to do any of that strip units stuff to generate six new variables, two for each button size
- Using sibling selectors, we can target those split button dropdown toggles using the .dropdown-toggle-split class, and adjust padding and margin as needed
- Now, we nuke the margin-left from the ::after generated caret and tighten up the padding so that those split toggles don't look huge next to their main button
This avoids applying the reset to named anchors/placeholder links (links
without an `href`) that have explicitly been made keyboard-focusable
(using `tabindex`). This is not fool-proof - it's not
easy/straightforward to check for the actual `tabindex` value itself, to
ensure it's positive, not will this apply if a link has been "blessed"
with `tabindex` via JS. However, this should catch most common uses (and
gives a reasonably valid way around the issue for developers who, for
whatever reason, DO want to use links without `href` - as side effect,
it forces best practice of at least ensuring these links can also be
focused with the keyboard)
- Move disabled radio and checkbox styles to Reboot
- Collapse .radio and .checkbox into single class, .form-check
- Collapse .radio-inline and .checkbox-inline into single class, .form-check-inline
- Require classes for sub-elements in both new classes
- Drops the experiment I had going for `box-shadow`-powered borders
- Reinstates regular `border` using existing variables
Fixes #19097 and #19143. Nullifies #19828.
- Rather than use CSS hacks, let's avoid needing to hack anything
- Creates a new Reboot entry to simply reset the appear of the temporal inputs, thereby avoiding the problem entirely
- Less than ideal for conveying affordance on iOS, but given bugginess of the input itself, seems a decent tradeoff
