Basic Examples

Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.

Raised Buttons

Add shadow effects to the buttons by adding the .btn--raised

Button Tags

The .btnclasses 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).

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.

Icon buttons

You can refer the Icons page for the complete list of Font Icons which are inspired by Material Design

Floating action buttons

Floating action buttons represents the primary action in an application. Only one floating action button is recommended per screen to represent the most common action.

You can check the Floating Action Buttons bottom right in the below pages.

Sizes

Fancy larger or smaller buttons? Add .btn-lgor .btn-smfor additional sizes.

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

Button State

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 <button>s as they use a pseudo-class. However, you can still force the same active appearance with .active(and include the aria-pressed="true" attribute) should you need to replicate the state programmatically.

Disabled state

Make buttons look inactive by adding the disabled boolean attribute to any <button>element.

Button group

Group a series of buttons together on a single line with the button group

Basic example

Wrap a series of buttons with .btnin .btn-group

Button toolbar

Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more.

Sizing

Instead of applying button sizing classes to every button in a group, just add .btn-group-*to each .btn-group, including each one when nesting multiple groups.

Nesting

Place a .btn-groupwithin another .btn-groupwhen you want dropdown menus mixed with a series of buttons.

Button plugin

Control button states or create groups of buttons for more components like toolbars.

Toggle states

Add data-toggle="button"to toggle a button’s activestate. If you’re pre-toggling a button, you must manually add the .activeclass and aria-pressed="true"to the <button>.

Single toggle

Checkbox and radio buttons

Bootstrap’s .buttonstyles can be applied to other elements, such as <label>s, to provide checkbox or radio style button toggling.
