First you might want to try using src="./css/main.css".
When dealing with multiple live sites I like to setup a single configuration file for each site with apache and then load them all together in the httpd.conf file.
for my setup it looks like this:
in
/etc/apache2/httpd.conf
I have:
# Begin virtual host directives.
Include conf/bortreb.conf
Include conf/rlmcintyre.conf
Include conf/laserkard.conf
Include conf/judyates.conf
and then in
/etc/apache2/conf/judyates.conf
I have:
<VirtualHost *:80>
#localhost site
ServerAdmin [email protected]
DocumentRoot "/home/r/Desktop/web/judyates"
ServerName localhost
ServerAlias judyates.localhost
ErrorLog "/home/r/Desktop/web/judyates/log/error_log.log"
ScriptAlias /cgi-bin/ "/home/r/Desktop/web/judyates/cgi-bin/"
<Directory "/home/r/Desktop/web/judyates">
Options Indexes FollowSymLinks
Options +ExecCGI
AddHandler cgi-script cgi pl py
AllowOverride Options
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
<VirtualHost *:80>
#live site
ServerAdmin [email protected]
DocumentRoot "/home/r/Desktop/web/judyates"
ServerName judyates.com
ServerAlias *.judyates.com
ErrorLog "/home/r/Desktop/web/judyates/log/error_log.log"
ScriptAlias /cgi-bin/ "/home/r/Desktop/web/judyates/cgi-bin/"
<Directory "/home/r/Desktop/web/judyates">
Options Indexes FollowSymLinks
Options +ExecCGI
AddHandler cgi-script cgi pl py
AllowOverride Options
Order allow,deny
Allow from all
</Directory>
</VirtualHost>
This way works really well, because you can set the subdomain yoursite.localhost
to loop back to your home ip address.
With this setup, when I work on judyates.com on my computer and want to test anythig, I just go to judyates.localhost in my web browser.
I have about 5 other sites all set up this way in their own *.conf file, so they can each live in their own directories on my computer that exactly match the directories they'll be in on the server.
The key is to use virtual hosts to go to different sites based on the subdomain.
You can learn how to configure subdomains that point to yourself here:

My setup goes even one step further because I setup the server too. Whenever I want to update I load both the webfiles AND the apache config files, and that way the server exactly mirrors my local setup. The only difference is that the real judyates.com points to the server and not my home computer, so when people try to visit the site they get everything from the server.
