I ask because we discovered one of our pages had a <head> > tag, but no </head> tag, and it validated okay, which surprised us. Yes, no problem. If you don't like it, you can run your HTML through a normaliser (e.g. sgmlnorm), use a DTD tweaked to make these tags mandatory, or use XHTML which always makes them mandatory. > (http://www.w3.org/TR/html4/struct/global.html#edef-TITLE) says "Every HTML > document must have a TITLE element in the HEAD section.", but if the head > tag is entirely optional anyway, what do we do about title? These things The HEAD is not omitted when you parse the document. It is implied. To see this, take a valid page that omits one or more of these tags, and validate it using the Visual Validator at <URL:http://valet.webthing.com/page/>. It will show you normalised source, including the omitted tags. -- Nick Kew Site Valet - the mark of Quality on the Web. <URL:http://valet.webthing.com/>
