Button elements

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

Button rounded

In need of a button, but not the hefty background colors classes with the .btnand plus custom class.btn-rounded.

Button Outline

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-Block

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

Dropdown Button

Any .btncan be turned into a dropdown toggle with some markup changes. Here’s how you can put them to work with either&ltbutton>elements:

Dropup

Trigger dropdown menus above elements by adding .dropupto the parent element.

Button Group

Wrap a series of buttons with .btnin .btn-group. Combine sets of button groups into button toolbars for more complex components. Use utility classes as needed to space out groups, buttons, and more.

Button Size

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

Button Disabled

Make buttons look inactive by adding thedisabledboolean attribute to any &ltbutton>element.

Dropdown Size

Button dropdowns work with buttons of all sizes, including default and split dropdown buttons.

Split Dropdown Button

Similarly, create split button dropdowns with virtually the same markup as single button dropdowns, but with the addition of .dropdown-toggle-splitfor proper spacing around the dropdown caret.

Checkbox - Radio Buttons

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