Hi All

We are finding more and more clients are struggling to overcome F3 of WCAG 2.0 (Failure of Success Criterion 1.1.1 due to using CSS to include images that convey important information). Essentially they are using CSS Sprites for buttons and other important images that are not visible in Windows High Contrast Mode.

Does anyone know of an easy way around this for complex and large websites that are not planning a redesign? Steve provided some great insights in his article 'High Contrast Proof CSS Sprites' via the before: pseudo element (http://www.paciellogroup.com/blog/2010/01/high-contrast-proof-css-sprites/). Anyone have any advances on this or similar solutions they recommend?

Many thanks in advance.
