What are common accessibility mistakes?
While certainly not an exhaustive list, the following is representative of many common accessibility mistakes. Note that many, if not most, of these can be found and fixed by writing your web pages in XHTML and running them through an HTML validator. • images without alternative text • lack of alternative text for imagemap hot-spots • audio or video without captions or transcripts • lack of alternative information for users who can’t access frames or scripts • tables that are difficult to decipher when linearized • sites where color is the only way to distinguish elements, or with poor color contrast • fonts that are fixed-sized.
