Consider providing a means for screen readers to bypass navigation bars repeated at the beginning of each page. Use the HTML headings in the correct order . H1 is the largest and is used first. Some browsers provide an outline to a page based on the content of the headings. If you use frames , provide titles for each frame and provide a noframe alternative.
Titles provide the user with a means to identify which frame to go to.
Some users, even those without special needs, dislike frames due to difficulty printing a frame and difficulty bookmarking a frame. Use tables with care . Wave is a useful tool for seeing how the contents of a table will be read. Select colors carefully . Even a person without a color deficiency may have a problem reading it.
