I am trying to use mod_rewrite to remove a leading '/' on a relative link, so that:

HTML Code:
	<link rel="stylesheet" type="text/css" href="/css/nav.css" media="all" />
becomes:
HTML Code:
	<link rel="stylesheet" type="text/css" href="css/nav.css" media="all" />
(no '/' before the css directory).

I've tried several variations around:
Code:
RewriteEngine on
RewriteRule ^/css/(.+)$ css/$1
but nothing seems to work (I have checked that the Rewrite Engine is on).

Can someone put me right, please.
