Native CSS Only Editor

Clip bug Firefox

Overlapping clipping doesn't clip (hide). In a way it has logic as - - = +, but doubt that should apply here.

The clip-path CSS property creates a clipping region that sets what part of an element should be shown. Parts that are inside the region are shown, while those outside are hidden.

animate clipping
clipping class .clip

Chromium does it right IMHO.
