I think the BR one's right, to be honest. If you were new to the language, and saw:<B>text</B><I>text</I>etc..you'd think it'd be<BR></BR>Which is where it becomes confusing... <BR /> is a nice way of sorting out "self-closing" tags, like <base /> etc.Center is a bit of a weird tag. I personally love it, and use it all the time. IMG is being depricated in the next XHTML isn't it?I agree that XHTML / XFORMS need to be taken with a pinch of salt, but the language is only at 1.0/1.1, i suppose.http://www.ajaxian.com/archives/2005/06/html_5_vs_xhtml.htmlA nice article
