Pure CSS3 Toggle Checkbox

Terinspirasi dari karya UmbrUI oleh Simurai. Yang ini adalah versi cross browser:

HTML 

<span class="toggle">
    <input type="checkbox">
    <label data-off="&#10006;" data-on="&#10004;"></label>
</span>

<span class="toggle">
    <input type="checkbox">
    <label data-off="&#9724;" data-on="&#9654;"></label>
</span>

<span class="toggle">
    <input type="checkbox">
    <label data-off="Stop" data-on="Play"></label>
</span>
