Animated Checkbox with CSS3 Powered Animation

An animated checkbox made by Jimmy Gillam that animates the ‘check’ action using CSS3 transforms and keyframe animations. Only an input and a label, and no javascript needed! Or without an input, just add the class “checked” to start the animation. Tested with: IE9+, Chrome, FF

How to use it:

Create an input and a label for the animated checkbox.

<input type="checkbox" id="cbtest" />
<label for="cbtest" class="check-box"></label>

The CSS/CSS3 rules.
