A CSS technique, sadly, to be avoided

Many of the beautiful designs at the CSS Zen Garden rely on a trick that’s been dubbed Farhner Image Replacement. In the best of worlds, this trick would actually enhance accessibility, but the reality is that at least one screen reader (JAWS, the market leading screen reading tool.) breaks it. As such, I have to avoid using the trick myself and I will have to advise customers to avoid it as well.
