If you've ever created a Web site without any CSS codes, you've most likely used a lot of < font > and other tags to control how your pages look. This ties the presentation of your site with its content, making it hard to modify your Web site design. If you later decide to change the color scheme or fonts used in your site, you'll have to edit every page in order to do this.

Cascading style sheets (CSS) provide a solution to this problem. Instead of defining the Web site design in each and every page, you can use a style sheet to control the overall layout of your site. Then if you want to change how your site looks, you simply modify the style sheet.
