Use CSS For Better Organic Search Rankings
CSS makes your Website SEO friendly as Google, Yahoo and MSN love light-weighted Web sites. They want to see your content; the text, not the code.
Search engines spiders are actually lethargic. They don’t go through the bundles of HTML code to get to the indexed codes. Font tags and tables make HTML code cumbersome, and thus reduce the accuracy of the results.
For instance, you could easily make the main content of your site to show up above the header or navigation menu in the code of your Web site; this will help to show search engine crawlers the importance of your content. Link
