Disable custom CSS at a point??

[liamwli]

So, I have been making a new simple style that incorporates the main site header.

I am getting there with it, but the CSS used breaks the other parts of the forum

See here for what I mean: http://community.mehost.co.uk/forum.php?styleid=8

I have added the header code into the header template. At the very top of the header template, I added links to the CSS files (which are located at the http://mehost.co.uk domain).

Is there anyway to disable the linked css files at the end of the header template? If not, could someone tell me how to achieve what I want?
