Description

CSS Masks seem fairly neglected. There are cool things like mask-mode which doesn't work on chrome.

Rationale

Support meets an MVP level, but the more advanced features (like mode) are inconsistent, and the prefixed versions only complicate the matter. I'd love to be able to use this one any evergreen browser without needing to test behavior on each browser individually.

Specification

W3C

Tests

Each of these properties are implemented in each browser:
mask-clip
mask-composite
mask-image
mask-mode
mask-origin
mask-position
mask-repeat
mask-size
