Neil, > 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/ > <http://www.paciellogroup.com/blog/2010/01/high-contrast-proof-css- > sprites/> ). Anyone have any advances on this or similar solutions they > recommend? You will find some basic solutions here: * Links: http://www.barrierefreies-webdesign.de/knowhow/symbole/download/css-sprites- mit-links-und-content.zip * Buttons: http://www.barrierefreies-webdesign.de/knowhow/symbole/download/css-sprites- mit-button-und-content.zip There is a lot to write about icons, CSS sprites and accessibility. Unfortunately, I can only offer it in German: http://www.barrierefreies-webdesign.de/knowhow/symbole/ The bottom line is that * yes, you can get your icons displayed in high contrast mode with CSS adaptions * but even if you do, there are still considerations needed to be made for screenreader usage. If icons and other images are not purely presentational, then they belong in HTML with alternate text. And if they are purely presentational, then there are still some accessibility reasons to keep them in HTML. As far as your question is concerned: You are referring to 1.1.1 and that is about alternate text, not high contrast mode. If images require an alternate text and are thus placed in HTML, then they will be displayed in high contrast mode as well.
