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.
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>
<button type="button" class="btn btn-gray">Gray</button>
<button type="button" class="btn btn-link">Link</button>
Disable text wrapping
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.
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.
<a class="btn btn-primary" href="#" role="button">Link</a>
<button class="btn btn-primary" type="submit">Button</button>
<input class="btn btn-primary" type="button" value="Input">
<input class="btn btn-primary" type="submit" value="Submit">
<input class="btn btn-primary" type="reset" value="Reset">
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.
<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>
<button type="button" class="btn btn-outline-Gray">Gray</button>

Disabled state
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.
<button type="button" class="btn btn-lg btn-primary" disabled>Primary button</button>
<button type="button" class="btn btn-gray btn-lg" disabled >Button</button>
Disabled buttons using the <a>
element behave a bit different:
<a>
s don’t support thedisabled
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. - Disabled buttons should include the
aria-disabled="true"
attribute to indicate the state of the element to assistive technologies.
<a href="#" class="btn btn-primary btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Primary link</a>
<a href="#" class="btn btn-gray btn-lg disabled" tabindex="-1" role="button" aria-disabled="true">Link</a>
Block buttons
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.
<div class="d-grid gap-2">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
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.
<div class="d-grid gap-2 d-md-block">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
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.
<div class="d-grid gap-2 col-6 mx-auto">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
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.
<div class="d-grid gap-2 d-md-flex justify-content-md-end"">
<button class="btn btn-primary" type="button">Button</button>
<button class="btn btn-primary" type="button">Button</button>
</div>
Toggle states
Add data-bs-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 ensure that it is conveyed appropriately to assistive technologies.
<button type="button" class="btn btn-primary" data-bs-toggle="button" autocomplete="off">Toggle button</button>
<button type="button" class="btn btn-primary active" data-bs-toggle="button" autocomplete="off" aria-pressed="true">Active toggle button</button>
<button type="button" class="btn btn-primary" disabled data-bs-toggle="button" autocomplete="off">Disabled toggle button</button>
<a href="#" class="btn btn-primary" role="button" data-bs-toggle="button">Toggle link</a>
<a href="#" class="btn btn-primary active" role="button" data-bs-toggle="button">Active toggle link</a>
<a href="#" class="btn btn-primary disabled" tabindex="-1" aria-disabled="true" role="button" data-bs-toggle="button">Disabled toggle link</a>
Methods
You can create a button instance with the button constructor, for example:
var button = document.getElementById('myButton')
var bsButton = new bootstrap.Button(button)
Method | Description |
---|---|
toggle
|
Toggles push state. Gives the button the appearance that it has been activated. |
dispose
|
Destroys an element's button. (Removes stored data on the DOM element) |
getInstance
|
Static method which allows you to get the button instance associated to a DOM element, you can use it like this: bootstrap.Button.getInstance(element)
|
getOrCreateInstance
|
Static method which returns a button instance associated to a DOM element or create a new one in case it wasn't initialised.
You can use it like this: bootstrap.Button.getOrCreateInstance(element)
|
For example, to toggle all buttons
var buttons = document.querySelectorAll('.btn')
buttons.forEach(function (button) {
var button = new bootstrap.Button(button)
button.toggle()
})
