Please add `.active` class to animate element without hovering

I like the animation in Hover.css. I would like to animate element without a need to hover on them.
For example:

.hvr-bob:hover, .hvr-bob:focus, .hvr-bob:active **, .hvr-bob.active** {
```
    -webkit-animation-name: hvr-bob-float, hvr-bob;
    animation-name: hvr-bob-float, hvr-bob;
    ...
```
}

So I just give `.active` class for choosen element.
