The Contrast interface is a HTML 5-based browser application based on AngularJS, and works well with the latest version of any modern browser. Contrast actively tests the interface with the following browsers and versions:
- IE 11+
(After December 2017, Contrast no longer supports IE 10.)
- Safari 8+
- Chrome 40+
- Firefox 37+
Opera and older versions of Firefox, IE, and Safari browsers may still operate well, but some features might not display as intended.
