FaT guidelines and compliance

Web browser compatibility

FaT works in all major web browsers, and has specifically been verified to function in:

  • Firefox
  • Safari 1.3+
  • Internet Explorer 5.x+
  • Opera 9+

Fading effects

The proprietary DXImageTransform.Microsoft.Alpha is used for Internet Explorer and works from version 5.5 and up. For the rest of the web browsers, the CSS 3 property opacity is being used, and currently it is supported by Gecko-browsed web browsers (Firefox, Mozilla, Camino etc) and Safari.

Accessibility

All the events and behavior are applied unobtrusively from an external JavaScript file. To create a fallback for non-JavaScript users, anchor links are recommended for any element that will trigger focus on any other element in the web page.
