This demo is actually pretty practical. It shows how you can help emphasize the action of a button by scaling it.
In non-webkit browsers, it does nothing because we used scale instead of a transform on width/height.
Button styling came from the excellent demos created by the
Slider Rotate Demo
This shows how to attach a transform to the action of a slider. There's a .6 second transition built into the rotation of
the box. Essentially, the slider callback invokes a CSS property change.
Animated Opacity Demo
This demo changes the opacity of the container on hover, and is animated at .5s. Fairly simple but dramatic effect.
