Header on blog not consistent with rest of website

Hey all,

So I basically copied the same code from my website into the blog .php files. The footer and body work just fine in both the blog and the website, but the header is acting weird in the blog page. The main website is just fine. The color is fine, but the background banner is missing and the font is not aligned properly. Below are links to (I believe) everything you would need, but let me know if you need something else. Thanks ahead of time.

Main Website
Example with page with smaller banner (the one I would like to see in the blog page)
Blog
Blog CSS
Blog Header
Right-click and view the source for the home and music page.
