About the "QA Tips"

The W3C QA Tips are short documents explaining useful bits of knowledge for Web developers or designers, hosted and produced by the Quality Assurance Interest Group at W3C.

Learn more about the Tips, how to submit your own pearls of wisdom, and find all the other QA tips in the Tips Index.
