Hi,
I plan to use CSS with CMS on my website. I would like to use CSS content management system for the inherent benefits of managing my website myself. I have seen a few websites developed by Image Works Studio using CSS CMS together in a very correct manner. Can any of you please guide me what CSS content management system they have used?
Can you point me to any online resources that help in using CMS and CSS to develop a website and make it SEO friendly. 

Thank You,
