Bootstrap includes six predefined button styles, each serving its own semantic purpose.
Replace the default modifier classes with the .btn-outline-*
ones to remove all background images and colors on any button.
Use class .btn-rounded
for button round border.
Use class .btn-rounded
for button round border.
Add .btn-lg
or .btn-sm
for additional sizes.
Add .w-xs
, .w-sm
, .w-md
and .w-lg
class for additional buttons width.
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).
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 andaria-pressed="true"
to the <button>
.
Create block level buttons—those that span the full width of a parent—by adding .btn-block
.
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.
Wrap a series of buttons with .btn
in .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.
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.
Make a set of buttons appear vertically stacked rather than horizontally. Split button dropdowns are not supported here.
