Use Bootstrap’s custom button styles for actions in forms,dialogs,and more with support for multiple sizes,states,and more.
Basic
Bootstrap includes several predefined button styles,each serving its own semantic purpose,with a few extras thrown in for more control.
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.
Sizes
Fancy larger or smaller buttons? Bootstrap offers different size buttons for your taste.
Block Buttons
Create block level buttons—those that span the full width of a parent—by adding .btn-block.
Disabled State
Make buttons look inactive by adding the disabledboolean attribute to any <button>element.
Rounded Buttons
Use .rounded-pillclass from Bootstrap utilities to create rounded buttons.
