Does anyone know of this holy grail? REM & EM http://www.w3.org/WAI/GL/css2em.htm http://www.w3.org/TR/css3-values/#font-relative-lengths The magic is that the user is in position to customize his personal computing device if and when he finds the base font size in his browser is inappropriate. No designer is in position to do better, no matter how many things he might fetch from the DOM. The designer who sticks to sizing only contextually, leaving the base size at the user's specification, is doing the best job for accessibility. The relationship to print isn't necessarily useful. A major advantage of the web is the absence of necessity to fit content to a known size of output medium. Browsers inherently adapt to the wide variation of available viewport space in users' agents. Web user space adapts to user needs in ways no other medium can compare to. Web designer use of CSS typically limits that adaptability, reducing accessibility as a result. IOW, if you resist the temptation to try to make the web look like cookie-cut magazine pages, you maximize accessibility, and user experience. -- "The wise are known for their understanding, and pleasant words are persuasive."
