Curious how the page can look with different high contrast mode? With
svg and filters like
feComponentTransfer it is possible to apply different filter variations to the page. Check out a new version v.0.0.858 of ASLint to see how it works.
The feature has been tested on Firefox 53.0.3 (64-bit) OSX, Chrome 58.0.3029.110 (64-bit) OSX, Safari 10.1.1 (12603.2.4) OSX.
