Chris@0:  * Buttons.
Chris@0:  *
Chris@0:  * 1. Enable z-index on buttons.
Chris@0:  * 2. Normalize 'line-height'; can’t be changed from 'normal' in Firefox 4+.
Chris@0:  * 3. Allows full range of styling in Webkit and Gecko.
Chris@0:  * 4. Use px units to ensure button text is centered vertically.
Chris@0:  * 5. Use rems to avoid the font size cascade of ems, with a px fallback for
Chris@0:  *    older browsers.
Chris@0:  * 6. Prevent fat text in WebKit.
Chris@0:  *
Chris@0:  * @todo Consider moving box-sizing into base.css under a universal selector.
