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.

<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-white">White</button>
<button type="button" class="btn btn-dark">Dark</button>
<button type="button" class="btn btn-link">Link</button>

Button soft

<a class="btn btn-primary-soft" href="#">Primary</a>
<a class="btn btn-dark-soft" href="#">Dark</a>
<a class="btn btn-light-soft" href="#">Light</a>
<a class="btn btn-secondary-soft" href="#">Secondary</a>
<a class="btn btn-success-soft" href="#">Success</a>
<a class="btn btn-danger-soft" href="#">Danger</a>
<a class="btn btn-warning-soft" href="#">Warning</a>
<a class="btn btn-info-soft" href="#">Info</a>

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 icons and round

<a class="btn btn-primary" href="#"><i class="fas fa-info-circle me-2"></i>Primary</a>
<a class="btn btn-dark" href="#">Dark <i class="fas fa-angle-right ms-2"></i></a>
<a class="btn btn-primary btn-round btn-sm" href="#"><i class="fas fa-play"></i></a>
<a class="btn btn-primary btn-round" href="#"><i class="fas fa-play"></i></a>
<a class="btn btn-primary btn-round btn-lg" href="#"><i class="fas fa-play"></i></a>

Button icon hover scale

Button link
<button class="btn btn-dark icon-link icon-link-hover" href="#">Button<i class="bi bi-arrow-right"></i> </button>
<a class="btn btn-link icon-link icon-link-hover" href="#">Button link<i class="bi bi-arrow-right"></i> </a>

Button sizes

<a class="btn btn-primary btn-xs" href="#">x Small</a>
<a class="btn btn-primary btn-sm" href="#">Small</a>
<a class="btn btn-primary" href="#">Default</a>
<a class="btn btn-primary btn-lg" href="#">Large</a>

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-secondary btn-lg" disabled>Button</button>

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.
  • 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-secondary 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>

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.

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-block">
	<button class="btn btn-primary" type="button">Button</button>
	<button class="btn btn-primary" type="button">Button</button>
<div class="d-grid gap-2 d-md-flex justify-content-md-end">
	<button class="btn btn-primary me-md-2" type="button">Button</button>
	<button class="btn btn-primary" type="button">Button</button>
