Examples

Bootstrap includes several predefined button styles, each serving its own semantic purpose.

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 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).

Link

Sizes

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

Disabled Buttons

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

Disabled Links

<a>s don’t support the disabled attribute, so you must add the .disabled class to make it visually appear disabled.

Block Buttons

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

Toggle states

Add data-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 the <button>.

Checkbox buttons

Bootstrap’s .button styles can be applied to other elements, such as <label>s, to provide checkbox or radio style button toggling. Add data-toggle="buttons" to a .btn-group containing those modified buttons to enable toggling in their respective styles.

radio buttons

Bootstrap’s .button styles can be applied to other elements, such as <label>s, to provide checkbox or radio style button toggling. Add data-toggle="buttons" to a .btn-group containing those modified buttons to enable toggling in their respective styles.

Input With Button Groups

Feel free to mix input groups with button groups in your toolbars. Similar to the example above, you’ll likely need some utilities though to space things properly..

Button Groups

Place a .btn-group within another .btn-group when you want dropdown menus mixed with a series of buttons.Make a set of buttons appear vertically stacked rather than horizontally.
