# CSS: Cascading Style Sheets

CSS is a new recommendation from the World Wide Web Consortium, W3C, that allows you more control over the look and layout of your HTML documents. The document you came from uses CSS to enhances the presentation.

Using CSS, you can influence:

- fonts, font sizes, font colors
- line spacing and length
- margins and indents
- background images and colors

and much more.

You can insert style sheets into documents or link to an external style sheet (referenced by a URL) that can influence many documents simultaneously.

Among the benefits of using CSS are:

- The HTML becomes much simpler to write and change
- You have finer control over presentation
- You can define the look of a site in one place, and change the whole site by changing just the one file
- People with simpler browsers can still see your pages
- People with disabilities have greater access to Web pages

CSS is implemented to date in several browsers, including Microsoft Internet Explorer 3, and Netscape Navigator 4.
