Last Updated : 12 Dec, 2021

Before performing with outline classes of bootstrap just know about a little bit of button outline. An outline on buttons means to give an outline around the buttons. This ‘.btn-outline’ class removes all background colors or styles from the button for giving the Effective, lighter, and highlighter look to the button outside. Basically, the outline button is responsible for drawn a highlighted border around the button.

Outline of buttons are used for many purposes such as –

To give an effective look at buttons.
To Indicate an action beyond the current working mechanism.
To draw highlight outlines around buttons to give different look than normal buttons.
To make a button “Stand-Out”.
To give different styles for actions in forms and dialogs.
