* Fix focus box shadow of custom ranges
* Put `:focus` selector right after `.custom-range`
* Remove unnecessary `outline: none`
* Fix box-shadow issues in IE/Edge
* Better align
* Fix thumb vertical positions in IE/Edge
* Fix incorrect formula of thumb vertical positions in Webkit
* Fix an incorrect comment
* Fix incorrect box-shadow-width
Now `.custom-control` will have height equal to `$font-size-base`
Fix custom checkbox and radio top position (we can't subtract rem from unit)
`$line-height-base - $custom-control-indicator-size` is not valid
Because `$line-height-base` is a unitless variable and `$custom-control-indicator-size`
is a unit (rem) variable
- Only applies to textual inputs and textareas with `.form-control` and selects with `.custom-select`
- Wrap the feedback icons in a Sass variable option, $enable-validation-icons, so folks who theme can disable
- Update docs to summarize styles, mention the icons, include a textarea demo, and add mention of the Sass variable option to the Theming section
- Fixes#25656 where custom selects had the wrong focus shadow
- Fixes#26668 where custom selects had no inset shadow (also closes#26572 which had the wrong form classes on the first example anyway)
* added the styling
* added the documentation
* update for one rule per line
* fix hound error: trailing whitespace
* trimmed off vendor prefixes
* Add note about track and thumb
* Psuedo-elements must be split across multiple rulesets to have an affect
* Fix firefox inner focus
* Seems that FF is the only one affected by this
* Add support for gradients
* Add labels, clarify min/max changes
* add step example
* add custom range vars
- Changes the wrapping label to a div so we can style the label instead of another element while also supporting form validation.
- Fixes form validation styles for custom file input (closes#24831).
- Updates docs with validation styles (also adding example feedback text while I was there) and new how it works section.
* match layout behaviors
* ditch the indicator as separate element for psuedo-elements on the label
* move disabled to attribute only on input
* redo default inline check to support new markup
* redo inline forms
* clean up vars
* update validation mixin to new structure
* update checks in docs
* linting for for/id attributes
* Add support for size attribute on custom selects
* Add large custom select, document it and the small variant
* fix custom select focus state
* fix custom file input focus styles
* remove empty line
* Rewrite custom form check backgrounds
Previously, this was all just a background-color and background-image. When we restored the gradients though, we had two background-images competing on the same element, causing rendering glitches. This refactors that code, creating a mixin to simplify things, so we can we easily use two background-images (SVG icon and gradient) when -gradients is set to true.
Fixes#24598
* restore default vars
* Revamp custom check and radio backgrounds
Instead of applying multiple background-image's to the same element, we're adding a new ::before pseudo-element to layer the background-images. Gradients go on the .custom-control-indicator while their icons go on the ::before element. This allows us to shave some bytes from when we compile and we previously needed to redeclare the background-image for the icon if you changed the gradient.
* remove now unused mixin
* mention change in migration docs
* 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
