CSS which stands for Cascading Style Sheets is used in web design to separate the layout and content from presentation. Quite simply, style sheets allow the designer to specify colors and placement of objects like text in a single place rather than inside the webpage (HTML) itself. This makes it much simpler to make site wide changes and a designer can completely change the look of the site with some fairly straightforward changes in the CSS document which nothing more than a text file. CSS allows complete and total control over the style of a hypertext document. Style definitions are nothing new and are used in word processing programs like Microsoft WORD ,for instance, but CSS is much more powerful and is uniquely desined for the web application. The only way this can be illustrated in a way that gets people excited is by demonstrating what it can truly be, once the reins are placed in the hands of those able to create beauty from structure.
In summary, style sheets can save a lot of work. Sheets define HOW HTML elements are to be displayed, just like the font tag and the color attribute in HTML 3.2. Styles are normally saved in external .css files. External style sheets enable you to change the appearance and layout of all the pages in your Web, just by editing one single CSS document! CSS is a breakthrough in Web design because it allows developers to control the style and layout of multiple Web pages all at once. As a Web developer you can define a style for each HTML element and apply it to as many Web pages as you want. To make a global change, simply change the style, and all elements in the Web are updated automatically.
