1. getElementById() works. 2. Validation. If you use <div id="maincontent">, validator will complain when you have two or more such divs (typical copy&paste accident :) Additionally IDs have higher priority than class in CSS, so it's easier to make "local" styles for element with an ID than with a class. -- regards, Kornel Lesiński ***************************************************** While true all those points had already been mentioned and weren't the point in any case.
