I have created a random background php script in my theme which is working. I want to do the same with my css. The only problem is how do I link it to my header?
With the random background script, I added <?php include("background.php");
?> before anything else in my header.php. I also added <body background="<?=$_SESSION['background']?>"> after </head>.
But with my CSS?
I know I have to include this <?php include("css.php");
But what about my $_SESSION['css']?
It should be added here somewhere? and how? href="<?php bloginfo('stylesheet_url'); ?>"
