Buttons
Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.
Examples
Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.

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.

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.

Sizes
Fancy larger or smaller buttons? Add .btn-lg or .btn-sm for additional sizes.

Create block level buttons—those that span the full width of a parent—by adding .btn-block.

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

Disabled state

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.

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.
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

Checkbox and radio buttons
Bootstrap’s .button styles can be applied to other elements, such as
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 or by manually applying the input’s checked property—you’ll need to toggle .active on the
