The HyperText Markup Language (HTML) is designed for the presentation of information on the World Wide Web, using a Web browser. HTML evolved from the need to share documents on the Internet and render them meaningfully on different browser platforms. It was originally created by Tim Berners-Lee when he was working on the first concepts of the Web at CERN in the late 1980s.
At FAO, the recommended HTML editors to create Web pages are Macromedia's Dreamweaver or HomeSite.
