I just found a detailed document on important differences between HTML and XHTML by the famous Ian Hickson, which is recommended for every web developer:
http://www.hixie.ch/advocacy/xhtml No, none of it is the trivia on replacing <IMG ...> with <img .../>. To quote a section: To embed CSS in an XHTML document which may be handled as either HTML4 or XHTML, you have to use: <style type="text/css"><!--/*--><![CDATA[/*><!--*/ ... /*]]>*/--></style> Yes, it's pretty ridiculous. If documents _aren't_ escaped like this, then the contents of <script> and <style> elements get dropped on the floor when parsed as true XHTML. roozbeh _______________________________________________ FarsiWeb mailing list [EMAIL PROTECTED] http://lists.sharif.edu/mailman/listinfo/farsiweb
