Previously deprecated in v4.x, this clears out the now unused Sass option and removes some unused mixins. Arguably we could remove more, but I like the hover-focus mixin and we make extensive use of it across the project.
- `background-position: 0 0;` is the default background position, so redundant
- The background position should only be animated in the x direction
- `0%` is a little shorter than `from`
- Line height & font family from html were directly overridden by body, so they were redundant thus removed
- The remaining properties are moved to body
- Shim for IE10 tags removed
- hr cleanup
- Combined styles from reboot & type
- Changed from borders to background
- This allows us to keep the color inherited.
- Opacity can be used to change the intensity
- Size attribute will not change the height instead of making the hr look like an input field
- Better variable names
- headings cleanup
- Moved all element styling to reboot
- Type will now extend the element styling. This way we will save some redundant code
- small & mark are also moved to reboot. type does not contain any element styling anymore
- font weight removed from small, this did not really made sense
Extrapolates the previously used selector into a new mixin that only generates valid CSS by creating psuedo-classes for `valid` and `invalid`, and nothing else.
Fixes#28380.
Currently, `$toast-border-radius` uses the value of `.25rem`. This is inconsistent with other variables such as `$btn-border-radius` and `$input-border-radius`, which uses the "global" `$border-radius` variable.
* Fix buttons :focus state styles
Buttons :hover and :focus state shares styles.
Buttons :focus text color on 'a.btn' is now consistent with others '.btn'.
* `:focus` styles should be in sync with `.focus`.
So shared styles with hover were copy to focus definition. Rather then using
`hover-focus` mixin which do not contain `.focus`.
- Drop hover and focus states
- Drop .badge-* variants and associated mixin for .bg-* utilities
- Drop .badge-pill for .rounded-pill utliity and adjust horizontal padding to find middle ground of .badge and old .badge-pill
- Remove unused variables
- Add default color value to .badge base class
- Update docs to reflect changes
instead, only apply outline suppression if the browser wouldn't normally apply the focus outline, using the (currently experimental) `:focus-visible` pseudo-class
