Hi!

You use structural markup like headings, paragraphs and lists. That's good. But you don't always nest them correctly. You should put a doctype on all pages. Then you can use the validator at this site or at w3c to check your documents. That's a great and time saving help.
http://htmlhelp.com/reference/html40/http://validator.w3.org/Look at the career page for instance.
http://www.htmlhelp.com/cgi-bin/validate.c...s&input=yesYou have a doctype on this page, but it's written wrongly. The URL part should be quoted.
http://www.htmlhelp.com/tools/validator/doctype.htmlWhen you have corrected that, the validator will show you other errors. Here's an example.
HTML
<SPAN style="font-family:Times New Roman;">
<p><h2><strong><em>Three of My Possible Career Choices</em></strong></h2></p>
SPAN (an inline element) can't contain block level elements like P and H2. Furthermore, P can only contain inline elements, so you can't have the H2 inside P.
http://htmlhelp.com/reference/html40/block.htmlYou can look each element up in the reference (there are clickable links in the validator report). If you look at SPAN it says this:
Contents: Inline elements
Contained in: Inline elements, block-level elements

HTML
<brl>
Give the validator a try and please ask if you don't understand its output. It can be hard to interpret the first times.
