I am new to CMS, WordPress and PHP so please forgive the ignorance but...
I am trying to alter the default theme drastically to fit the same structure I already have created for my new site. Yet most of the pages contain PHP references to data stored and I have no idea where the variable values are located. For example, the CSS reference is made via:
<link rel="stylesheet" href="<?php bloginfo('stylesheet_url'); ?>" type="text/css" media="screen" />
Where is the bloginfo located?
