The Ultimate HTML Reference should be on the desk of each and every web developer and designer. You never again have to wonder whether a browser supports a specific element or attribute, just page to the element, check the browser support stats, read the "fine print" and carry on with the job at hand. Not sure what the most appropriate element is to mark up a specific part of your page? Simple, the book is organized by groups of relevant elements such as Structural Elements, List Elements, Text Formatting etc.
