I Posted A thread About Search engine friendly links and i got results from your instrunctions so i changed my .htaccess to;

RewriteEngine On
RewriteRule ^(.*)/(.*)/(.*) $1.php?$2=$3

my css file is at http://ap-gfx.com/template/themes/style.css
and that is how i linked it to http://ap-gfx.com/index.php
i'm total gutted because i was on a roll on finishing my site but this has put me back a couple of days.
so if anybody knows how to make my layout appear and tell me what i've done please, please give ideas.

As I remember I gave you the rewrite rule. This was a general rule that would work for your particular problem. However if you had given more info I would suggested an alternative.,

RewriteEngine On
RewriteRule ^article/(.*)/(.*) article.php?$1=$2
RewriteRule ^index/(.*)/(.*) index.php?$1=$2

Yes, you must to write more exactly the rewrite rule, because all the files and directories are take by the rule and nothing will work
Only the archives that you want to apply the rewite rule you apply it, like maxxximus show.

so how would i link my css to index/category/php could youpost the example code to use for the css link
