MyBB Community Forums

I added my own header menu to the forums,
http://python-gaming.com/forums/

but as you can see in the website root
http://python-gaming.com/

the size of the text increases solely by adding it to the mybb forums. How can i lower this size back down to what the size of the menu should be. 

The code i added:
config.php

$config['header'] = file_get_contents('http://python-gaming.com/menu/menu.shtml');

and in ACP in header templates; header; i added in the beginning

{$mybb->config['header']}
<br>
<br>
<br>

The breaks because the forum image hid behind the menu bar.

Did you add anything to the CSS?

no i didnt

There is CSS for the menu bar
http://python-gaming.com/menu/menu-fixed.css

Upon looking i noticed after adding the menu too, that the links in the forums (search, member list, help, etc.) are showing only the inmage, but not the text as if i were to remove the menu bar.
