CSS breaks in Explorer

Thi开发者_JS百科s Wordpress site works fine in Firefox and Safari.

However viewing in Explorer 7 (don't care about 6) breaks the header/navigation area.

Weirdly enough, refreshing the page fixes the alignment issue, but then hides the header.

Any suggestions would be greatly appreciated.

First thing to do is fix your code errors: [Invalid]Markup Validation of anothersideof.me - W3C Markup Validator. Scroll down in the validation report to see line numbers and source code.

Then look into the differences in doctypes: What are the different doctypes in html and what do they mean? - Stack Overflow and how they work with IE.
