(1) take the current page's URL, (2) strip off the page part of that URL, back to the final slash in the URL and then (3) append the relative reference on the end.
(1) http://www.example.com/index.php
(2) http://www.example.com/
(3) http://www.example.com/style.css
Or are you saying
(2) http://www.example.com with no trailing slash,
which is where the relative 'style.css' got lost (http://www.example.comstyle.css)?\
The rewritten path BECOMES the web path, for the browser. The name, location and other identifying features of the resource being displayed is irrelevant to the browser ... it eats what the server feeds it.
The server fed it "/article/blah-blah", not "/index.php?p=123", therefore a request for "style.css" would be relative to the "/article" directory the browser "thought" it was in.
By using a server-relative link <img src="/img.src">, you tell the browser to remove both the page name and all subdirectory path-info from the page URL, and then append the "/img.src", making the image URL "example.com/img.src".
