Buttons
Use Bootstrap’s custom button styles for actions in forms, dialogs, and more with support for multiple sizes and states.
<button type="button" class="btn btn-primary">Primary</button>
<button type="button" class="btn btn-secondary">Secondary</button>
...Button tags
The .btn classes work with <button>, but you can also use them with <a> or <input>.
<a class="btn btn-outline-light" href="#">Link</a>
<input class="btn btn-primary" type="submit" value="Submit">Outline buttons
Use .btn-outline-* to remove background images and colors.
<button type="button" class="btn btn-outline-primary">Primary</button>

<button type="button" class="btn btn-primary btn-lg">Large button</button>
<button type="button" class="btn btn-secondary btn-sm">Small button</button>
