Default Buttons

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

Outline Buttons

Replace the default modifier classes with the .btn-outline-* ones to remove all background images and colors on any button.

Rounded Buttons

Use class .btn-rounded for button round border.

Buttons with icon

Add icon in button.

Snip Buttons

Buttons Sizes

Add .btn-lg or .btn-sm for additional sizes.

Buttons width

Add .w-xs, .w-sm, .w-md and .w-lg class for additional buttons width.

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).

Toggle states

Add data-bs-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>.

Block Buttons

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

Checkbox & Radio Buttons

Create button-like checkboxes and radio buttons by using .btn styles rather than .form-check-label on the <label> elements.

Button group

Wrap a series of buttons with .btn in .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.

Vertical variation

Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.
