While your <p> may work in most browsers this tag is supposed to have a closing tag</p> and may not work in some browsers.

</br> I'm not sure about. Maybe it will work in some browsers but it is incorrect. <br> is an empty tag that requires no end tag where </br> denotes and end tag for <br> which does not exist. It is supposed to be <br> or in XHTML or XML it would be <br /> since elements without a closing tag are not allowed.
