CSS website templates provide for smaller file sizes and faster browser rendering. By taking styles out of the HTML page and putting it into a standalone, imported style sheet also referred as a .css file, you can reduce the overall amount of code in your web pages.
CSS Templates allows you to structure your document according to HTML standards without compromising the look-and-feel of the page. Search Engines reward pages that are well structured, though many designers choose to ignore standards and guidelines as much as possible, because these standards sometimes lead to dull pages. CSS designers now can create attractive pages with much grace and style, while adhering to principal code validation.
