For example:
<button class="btn fill-bottom-warning">Warning</button>In the above example btn is from bootstrap classes and fill-bottom-warning is from the hover-on.
Important! It's necessary to suffix the class name with bootstrap color name like fill-both-primary. You don't need to add any suffix in 2d animation classes which are pop, push, float etc.
