I\'m wondering about the support for side specific inner shadows in css3.
I know this works great on supported browsers.
div { box-shadow:inset 0px 1px 5
box-shadow: inset 5px 0 5px -5px rgba(0,0,0,0.5),inset -5px 0 5px -5px rgba(0,0,0,0.5);
-moz-box-shadow: inset 5px 0 5px -5px rgba(0,0,0,0.5),inset -5px 0 5px -5px rgba(0,0,0,0.5);
-webkit-box-shadow: inset 5px 0 5px -5px rgba(0,0,0,0.5),inset -5px 0 5px -5px rgba(0,0,0,0.5);
-o-box-shadow: inset 5px 0 5px -5px rgba(0,0,0,0.5),inset -5px 0 5px -5px rgba(0,0,0,0.5);
This works just lovely :)
Here is a codepen illustrating it: http://codepen.io/poopsplat/pen/cGBLy
