Since the content-type says, this page is a HTML, not XHTML, page, this would lead IE <8 and many other old browser for misshandling the page.
HTML dosnt support self-colsing tags, event HTML5 dosnt (HTML5 re-implements optionaly end-.tags like HTML 3.2..).
So its nicly to see, agree, but not valid
As KeyWorld said , browsers even IE7 accepts this quite well, it doesn't even understand the doctype but it still works
see the screenshot
and believe me most IE users are from china , and I don't think anyone that knows eA is lazy ? enough to use an old outdated insecure browser
and what about other browsers? IE supports it right? yes you know what I mean lol ,
Just my opinion
Thanks
