Error with including stylesheet

[eluser]Tanax[/eluser]
Hi!

First of all, I have to say that I did not search for this on the forums, maybe I should've done that.

Anyhow!
I got a stylesheet, that I'm including in my header view:

Code:

<link rel="stylesheet" href="stylesheet.css" type="text/css" />

Simple.
It works GREAT when I'm on index:
http://localhost/

Btw, the stylesheet is in the same location as the index.php

It doesn't work when I'm navigating to the index:
http://localhost/site/index

I set the site to be default controller, and I allowed the stylesheet in the .htaccess:

Code:

RewriteEngine on
RewriteCond $1 !^(index\.php|images|robots\.txt|stylesheet\.css)
RewriteRule ^(.*)$ index.php/$1 [L]

Also worth to mention is that the controllers and URL thing works perfectly well. I see the view and everything. Only problem is that the css doesn't get applied to the pages if I go the controller via URL.

Any suggestions? Thanks in advance!
