Button Groups

Bootstrap 4 allows you to group a series of buttons together (on a single line) in a button group:

Use a <div> element with class .btn-group to create a button group:

Tip: Instead of applying button sizes to every button in a
group, use class .btn-group-lg for a large button group or the .btn-group-sm for a small button group:

Default Buttons:

Small Buttons:
