Material Style Toggle Switches with Pure CSS / CSS3

Material Design inspired on / off switches which allows the visitor to toggle the state by clicking  or tapping.  This technique makes use of the CSS pseudo elements, input label tricks and CSS3 transitions / transforms.

How to use it:

Create a checkbox input with a label that will be converted into a toggle switch.

<input type="checkbox" id="unchecked" class="cbx hidden"/>
<label for="unchecked" class="lbl"></label>

The core CSS / CSS3 styles & rules for the toggle switch.
