Examples

Bootstrap includes six predefined button styles, each serving its own semantic purpose.

Ghost Buttons

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.

Button tags

The .btn classes are designed to be used with the <button> element. However, you can also use these classes on <a> or <input> elements (though some browsers may apply a slightly different rendering).

When using button classes on <a> elements that are used to trigger in-page functionality (like collapsing content), rather than linking to new pages or sections within the current page, these links should be given a role="button" to appropriately convey their purpose to assistive technologies such as screen readers.

Link functionality caveat

The .disabled class uses pointer-events: none to try to disable the link functionality of <a>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.

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 <button>.

<button type="button" class="btn btn-primary" data-toggle="button" aria-pressed="false" autocomplete="off">
  Single toggle
</button>

Checkbox and radio buttons

Checkbox Radio button

Bootstrap’s .button styles can be applied to other elements, such as <label>s, to provide checkbox or radio style button toggling. Add data-toggle="buttons" to a .btn-group containing those modified buttons to enable toggling in their respective styles.

The checked state for these buttons is only updated via click event on the button. If you use another method to update the input—e.g., with <input type="reset"> or by manually applying the input’s checked property—you’ll need to toggle .active on the <label> manually.

Note that pre-checked buttons require you to manually add the .active class to the input’s <label>.

Checkbox 1 (pre-checked) Checkbox 2 Checkbox 3

Radio 1 (preselected) Radio 2 Radio 3
