It is included here to demonstrate rendering with Material Design for Bootstrap default styling. See the Material Design section for more elements and customization options. {% endcallout %} Use Bootstrap's custom button styles for actions in forms, dialogs, and more. Includes support for a handful of contextual variations, sizes, states, and more. ## Contents * Will be replaced with the ToC, excluding the "Contents" header {:toc} ## Examples Bootstrap includes six predefined button styles, each serving its own semantic purpose. {% example html %} {% endexample %} {% capture callout-include %}{% include callout-warning-color-assistive-technologies.md %}{% endcapture %} {{ callout-include | markdownify }} ## Button tags The `.btn` classes are designed to be used with the ` {% endexample %} ## Outline buttons In need of a button, but not the hefty background colors they bring? Replace the default modifier classes with the `.btn-outline-*` ones to remove all background images and colors on any button. {% example html %} {% endexample %} ## Sizes Fancy larger or smaller buttons? Add `.btn-lg` or `.btn-sm` for additional sizes. {% example html %} {% endexample %} {% example html %} {% endexample %} Create block level buttons—those that span the full width of a parent—by adding `.btn-block`. {% example html %} {% endexample %} ## Active state Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. **There's no need to add a class to ` {% endexample %} Disabled buttons using the `` element behave a bit different: - ``s don't support the `disabled` attribute, so you must add the `.disabled` class to make it visually appear disabled. - Some future-friendly styles are included to disable all `pointer-events` on anchor buttons. In browsers which support that property, you won't see the disabled cursor at all. - Disabled buttons should include the `aria-disabled="true"` attribute to indicate the state of the element to assistive technologies. {% example html %} Primary link Link {% endexample %} {% callout warning %} #### Link functionality caveat The `.disabled` class uses `pointer-events: none` to try to disable the link functionality of ``s, but that CSS property is not yet standardized. In addition, even in browsers that do support `pointer-events: none`, keyboard navigation remains unaffected, meaning that sighted keyboard users and users of assistive technologies will still be able to activate these links. So to be safe, add a `tabindex="-1"` attribute on these links (to prevent them from receiving keyboard focus) and use custom JavaScript to disable their functionality. {% endcallout %} ## Button plugin Do more with buttons. Control button states or create groups of buttons for more components like toolbars. ### Toggle states Add `data-toggle="button"` to toggle a button's `active` state. If you're pre-toggling a button, you must manually add the `.active` class **and** `aria-pressed="true"` to the ` {% endexample %} ### Checkbox and radio buttons Bootstrap's `.button` styles can be applied to other elements, such as `
