Relative link to CSS

I prefer not to use the base_url() thing because that just prints out www.example.com. Even if I changed it to localhost, it would be a hassle to change

set these settings in your config/config.php

Code:

$config['base_url'] = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == "on") ? "https" : "http");
$config['base_url'] .= "://".$_SERVER['HTTP_HOST'];
$config['base_url'] .= str_replace(basename($_SERVER['SCRIPT_NAME']),"",$_SERVER['SCRIPT_NAME']);

You shouldn't have to worry about ever editing that again. I know how much a pain moving from local to test to live and back again can be. Also, for the database i usually create three groups of setting for each environment. $db['local'], $db['test'], $db['live'], which you could set based on the info returned by the new automatic base_url();

Also, i'm not sure if this affects css/js links, but look into the html <base> tag. It tells every (relative) link on your page to be relative to that url. Its good because its supported by almost every browser and as easy as

Code:

echo '<base href="'.base_url().'"/>';

The downfall with it tho is that it will break your page anchors (#'s) unless they are either made absolute (using current_url() perhaps?) or modified by javascript to point to the page . (jQuery could prolly also provide a solution in less than 5 lines of code)
