Looks great. Very readable and easy to navigate. Good job.
Your index page has a large white space in the middle of the page. What are your plans for that?
On the technical side, I have a few comments.
- You appear to have a script testing for browser type and then serving a different image depending on the result. What was happening that made you that route?
- There is no DOCTYPE declared, so the document will not pass validation (http://validator.w3.org/) and throws the page into quirks mode for IE.
- Your style.css file has html tags <style> and </style>. They will prevent the file from working properly.
- The link to FIRST does not work use www.usfirst.org
Great job.
