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.
* 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`.
When gradients are enabled there is still a hover state on disabled
buttons since the hover rules apply to background-image and disabled
rules apply to background-color. This applies the logic already present
in dropdowns to buttons. This fix was originally proposed by @ysds.
* Fix Issue #24144
Alter button-outline-variant mixin to darken hover and active background in same fashion as filled button.
* Fix Issue #24144
Filled button on hover should utilize the same color-yiq mixin so that theme buttons match
* default values, fix mixin
* Update the form focus mixin to use a manual `$enable-shadows` check so we can always ensure a focus state for accessibility and consistency
* - Add new `$input-btn-focus-width` and `$input-btn-focus-color` variables.
- Replace separate `$btn-focus-box-shadow` and `$input-focus-box-shadow`
variables with unified `$input-btn-focus-box-shadow` to match our
combined variables approach elsewhere.
* Put new focus width var to use in buttons mixins
* use new button input-box shadow var
* Add a new mixin for quickly adding linear gradient to components when $enable-gradients is set to true
* use correct var
* fix focus shadows in button mixins
* Add opt-in gradients to alerts, buttons, carousel, custom radios and checkboxes, custom file input, and dropdown items
* Generate .bg-gradient- utilities
* add headings to colors page and document bg-gradient utils
* update the button color for active status, check with yiq as it's done for basic state and hover state
* Fixed some linting issues
* Run npm tasks after scss cleanup
* Revert "Run npm tasks after scss cleanup"
This reverts commit 1103a0da68.
* Property sort order for grid
* Let's respest the property order in the mixins
* Respect property sort order in reboot file
* ::-ms-expand is a vendor-prefix, add it to the scss-lint disable
* Revert hover mixin comment
* Fixed missing mixin hover-focus
- removes original outline removal (hah)
- replaces it with an explicit `outline: 0` on `.btn`
- instead of replicating `:hover` for `:focus`, uses custom and themed `box-shadow` for an "outline"
- not mapped to the `$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.
- Rename -height to -height-base to match other vars
- Drop use of -height across the board and rely on it to be inherited
- Adjust padding of .dropdown-header to account for different line-height of h6 heading element (this needs refactoring for variables and rems also)
If we want to support namespaced import:
```scss
.twbs {
@import 'bootstrap';
}
```
We cannot use `selector &`, see sass/sass#1817.
`fieldset[disabled] &` is not needed as we no longer support IE8.
