Please add .active class to animate element without hovering

[topex-psy]

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.
