Introduction

Style sheets for the Web have been proposed and developed for several years, but only recently have gained wide notice. The reason is that style sheets are useless unless browsers support them, and no widely used browser did until Microsoft began offering partial support for Cascading Style Sheets (CSS) in version 3.0 of the Internet Explorer. Support for style sheets is provided in IE 3.0 and higher, and in Netscape 4.0 and higher.

This section provides an overview of CSS, including the advantages of using style sheets, their limitations, and a guide to using them. This section itself uses style sheets, and if you have multiple browsers, you might want to compare the rendering of these pages in Internet Explorer (3.0 or higher) and another browser that doesn't support style sheets (Netscape 3.0 or earlier, for instance). Note that you will only be able to see the effects of the style sheets if you view the pages with Internet Explorer or Netscape Communicator 4.0 (or higher).
