And afterwards xhtml arrived together, with its XML rule that every aspect have to have a closing tag, and people just assumed that HTML was exactly the same point. And so the standards gave up, and had been later on revised to throw up their arms to the reality.
and render in a different way in a few browsers, so selecting both over another just isn't going to harm your job, but do count on a bulk locate.
