There was a question about the
br tag. How should you write it correctly:
</br> , or
<br /> ?
Depending on the specification: for DOCTYPE HTML it will be correct
<br> , for DOCTYPE XHTML –
<br /> . It is common for XHTML to put a slash before the closing parenthesis in single tags:
<br />, <hr />, <input /> , etc.
</br> is incorrect, because BR is a single tag, and the slash after the opening parenthesis is for closing descriptors only.
