* 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

Color
{% example html %} {% for color in site.data.theme-colors %}
.text-{{ color.name }}
{% endfor %}.text-muted
.text-white
{% endexample %}Contextual text classes also work well on anchors with the provided hover and focus states. Note that the .text-white and .text-muted class has no link styling.
{% example html %} {% for color in site.data.theme-colors %}
{{ color.name | capitalize }} link
{% endfor %} {% endexample %}Background color
Similar to the contextual text color classes, easily set the background of an element to any contextual class. Anchor components will darken on hover, just like the text classes. Background utilities do not set color, so in some cases you'll want to use .text-* utilities.
{% example html %} {% for color in site.data.theme-colors %}
Background gradient
When $enable-shadows is set to true, you'll be able to use .bg-gradient- utility classes. By default, $enable-shadows is disabled and the example below is intentionally broken. This is done for easier customization from moment you start using Bootstrap. [Learn about our Sass options]({{ site.baseurl }}/docs/{{ site.docs_version }}/getting-started/theming/#sass-options) to enable these classes and more.
{% example html %} {% for color in site.data.theme-colors %}
{% callout info %}
Dealing with specificity
Sometimes contextual classes cannot be applied due to the specificity of another selector. In some cases, a sufficient workaround is to wrap your element's content in a <div> with the class.
{% endcallout %}
{% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %} {{ callout-include | markdownify }}
