CSS Design
Web Designers are increasingly adopting cascading style sheets (css). The biggest draw to designers is the fact that it is table-less design. CSS allows far less code to be used, creating higher content-to-code-ratio. By using CSS, webmasters can clean up their code and arrange content at a higher (more accessible) portion of the page.
The end result is that search spiders are able to get through your site quickly, and easily differentiate content form code. Therefore, your website will be indexed accurately.
