Make glyphicon act as a button (style-wise)
<p>I wish to have a glyphicon that acts as a button when clicked, to have that inset effect.
When you press it to make it look as if its getting "pushed back" like a button</p>

<p>All I have so far is <code>.button-glyph:active { }</code> but I don't know what properties I can use to achieve the effect</p>
