Use of Cascading Style Sheets, or CSS, in web development is a technique that allows a website to separate it's content from its design. It can be used to define elements of the presentation of the documents such as color, font and layout. Separating the content reduces your websites load time, since the design doesn't have to download every time a new page is loaded. This also enables search engines to quickly index any new content that is posted on your website, which often leads to a competitive advantage over other websites that target the same audience as yours.
