Safari RSS is Apple’s default web browser for Mac OS X Tiger. As indicated by its name, it now features a built-in RSS (and Atom) reader. Aside from the powerful feed indicator and notification functions, Apple has created an elegant design as an alternative to complicated-looking XML-based feeds. While the XML format is intended to be human-readable, Apple has coated it over with blue accent gradients and hidden all the tags. For many users, this will be the defining look of RSS/Atom feeds.
We can make our RSS/Atom feeds look similar to the Safari RSS look. All we need is the proper CSS file linked as a stylesheet from our RSS/Atom XML file.
