We slice and style websites to reflect today’s standard (Web 2.0) in coding.  Rather than using just <table> tags to format page layout, we use <div> tags which is a very powerful tool for management and custom styling of  web pages with Cascading Style Sheets (CSS).  The advantage of using DIV and CSS is that the code that controls the layout of your pages(CSS) resides in a file separated from the content of your web pages.  When search engine spiders reaches your site, they will be more likely to index all the content in each page since the cumbersome <table> tags will be out of the way.
