Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes, states, and more.
Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.
If you don’t want the button text to wrap, you can add the .text-nowrap
class to the
button. In Sass, you can set $btn-white-space: nowrap
to disable text wrapping for each
button.
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.
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.
Fancy larger or smaller buttons? Add .btn-lg
or .btn-sm
for additional
sizes.
Make buttons look inactive by adding the disabled
boolean attribute to any <button>
element. Disabled buttons have pointer-events: none
applied to, preventing hover and
active states from triggering.
Disabled buttons using the <a>
element behave a bit different:
<a>
s don’t support the disabled
attribute, so you must add the
.disabled
class to make it visually appear disabled.
pointer-events
on anchor
buttons.
aria-disabled="true"
attribute to indicate the
state of the element to assistive technologies.
Create responsive stacks of full-width, “block buttons” like those in Bootstrap 4 with a mix of our display and gap utilities. By using utilities instead of button specific classes, we have much greater control over spacing, alignment, and responsive behaviors.
Here we create a responsive variation, starting with vertically stacked buttons until the md
breakpoint, where .d-md-block
replaces the .d-grid
class, thus nullifying the
gap-2
utility. Resize your browser to see them change.
You can adjust the width of your block buttons with grid column width classes. For example, for a
half-width “block button”, use .col-6
. Center it horizontally with .mx-auto
,
too.
Additional utilities can be used to adjust the alignment of buttons when horizontal. Here we’ve taken our previous responsive example and added some flex utilities and a margin utility on the button to right align the buttons when they’re no longer stacked.
