Description  

The overflow-clip-box CSS property specifies relative to which box the clipping happens when there is an overflow.

On Gecko, by default, padding-box is used everywhere, but <input type="text"> and similar use the value content-box. Prior to Firefox 29, this behavior was hardcoded; since then it uses this property that can be used elsewhere too. Note that this property is activated by default only in the UA stylesheet and chrome contexts.
