Hello
i checked m site on W3C and i got a few times the fault message:

Opening and ending tag mismatch: a line 515 and div ...</span></span></span></span></div></div></div></body></html>

Does this mean i have too much </div> or not enough or does this mean
</div> is not the correct ending tag?

Thank you in advance.
Sandra

you have a missing open tag or an extra closing tag somewhere

...or mismatched closing tags; for eg <div><span><span><a href="#">link</span></a></span></div>

It says "Line" on the error page just look at source and go to that line.

Not necessarily. That is where the fault occured the error will often be earlier in the document source.
