I'd be curious to see your validation errors. FYI, obsolete is brand new to HTML5, it's different than being deprecated, it means you can still use it but there's a probably a better way to do what you're trying to do and that you should abandon that old way for a better way but it's okay if you don't. Also if you would use the W3C validator you will see it only gives a warning about the summary but will still say your markup is valid so technically it's still valid markup to use summary. This is why all the experts I hear talk say if you have valid HTML or XHTML just changing your doctype to <!doctype html> gives you valid html5 markup. -- ------------------------------------------------------------------------------------ Jason Arnold http://www.jasonarnold.net ------------------------------------------------------------------------------------ ******************************************************************* List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: memberh...@webstandardsgroup.org *******************************************************************
