Use any of the available button classes to quickly create a styled button.

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

<p> <button type="button" class="btn btn-primary btn-lg">Large button</button> <button type="button" class="btn btn-default btn-lg">Large button</button></p><p> <button type="button" class="btn btn-primary">Default button</button> <button type="button" class="btn btn-default">Default button</button></p><p> <button type="button" class="btn btn-primary btn-sm">Small button</button> <button type="button" class="btn btn-default btn-sm">Small button</button></p><p> <button type="button" class="btn btn-primary btn-xs">Extra small button</button> <button type="button" class="btn btn-default btn-xs">Extra small button</button></p>			

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

<button type="button" class="btn btn-primary btn-lg btn-block">Block level button</button><button type="button" class="btn btn-default btn-lg btn-block">Block level button</button>			

Active state

Buttons will appear pressed (with a darker background, darker border, and inset shadow) when active. For <button> elements, this is done via :active. For <a> elements, it's done with .active. However, you may use .active on <button>s should you need to replicate the active state progammatically.

Button element

No need to add :active as it's a pseudo-class, but if you need to force the same appearance, go ahead and add .active.

<button type="button" class="btn btn-primary btn-lg active">Primary button</button><button type="button" class="btn btn-default btn-lg active">Button</button>			

Anchor element

Add the .active class to <a> buttons.

Primary link Link

<a href="#" class="btn btn-primary btn-lg active" role="button">Primary link</a><a href="#" class="btn btn-default btn-lg active" role="button">Link</a>			

Disabled state

Make buttons look unclickable by fading them back 50%.

Button element

Add the disabled attribute to <button> buttons.

<button type="button" class="btn btn-lg btn-primary" disabled="disabled">Primary button</button><button type="button" class="btn btn-default btn-lg" disabled="disabled">Button</button>			

Cross-browser compatibility

If you add the disabled attribute to a <button>, Internet Explorer 9 and below will render text gray with a nasty text-shadow that we cannot fix.

Anchor element

Add the .disabled class to <a> buttons.

Primary link Link

<a href="#" class="btn btn-primary btn-lg disabled" role="button">Primary link</a><a href="#" class="btn btn-default btn-lg disabled" role="button">Link</a>			

We use .disabled as a utility class here, similar to the common .active class, so no prefix is required.

Link functionality not impacted

This class will only change the <a>'s appearance, not its functionality. Use custom JavaScript to disable links here.

Context-specific usage

While button classes can be used on <a> and <button> elements, only <button> elements are supported within our nav and navbar components.

Button tags

Use the button classes on an <a>, <button>, or <input> element.


<a class="btn btn-default" href="#" role="button">Link</a><button class="btn btn-default" type="submit">Button</button><input class="btn btn-default" type="button" value="Input"><input class="btn btn-default" type="submit" value="Submit">			

Cross-browser rendering

As a best practice, we highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.

Among other things, there's a Firefox bug that prevents us from setting the line-height of <input>-based buttons, causing them to not exactly match the height of other buttons on Firefox.
