Buttons can be used to show the user’s choice of options for actions and assign these to a clear hierarchy. The target page to be accessed or the action to be triggered is shown on the buttons by means of a label in Type Wide Normal or else by an icon, or by a combination of the two. Good button labels are formulated in a way that is brief and precise. They tell the user exactly what action will be taken when the button is clicked. Buttons provide visual feedback when clicked or tapped, in the form of a response effect, providing that the buttons are not deactivated.

Bootstrap includes several predefined button styles, each serving its own semantic purpose, with a few extras thrown in for more control.

<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
<button type="button" class="btn btn-success">Success</button>
<button type="button" class="btn btn-danger">Danger</button>
<button type="button" class="btn btn-warning">Warning</button>
<button type="button" class="btn btn-info">Info</button>
<button type="button" class="btn btn-light">Light</button>
<button type="button" class="btn btn-dark">Dark</button>

<button type="button" class="btn btn-link">Link</button>

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.

<button type="button" class="btn btn-outline-primary">Primary</button>
<button type="button" class="btn btn-outline-secondary">Secondary</button>
<button type="button" class="btn btn-outline-success">Success</button>
<button type="button" class="btn btn-outline-danger">Danger</button>
<button type="button" class="btn btn-outline-warning">Warning</button>
<button type="button" class="btn btn-outline-info">Info</button>
<button type="button" class="btn btn-outline-light">Light</button>
<button type="button" class="btn btn-outline-dark">Dark</button>

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).

Primary Buttons

Use a .btn-primary button to call attention to an action on a form or to highlight the strongest call to action on a page.

<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-primary" disabled>Disabled</button>
<button type="button" class="btn btn-primary active">Selected</button>
