HyperText Markup Language, or HTML, is the language which controls the appearance of a web page. It instructs the web browser how to format and display the page. Basic HTML is simple to learn and use. In Netscape, select Help, How to Create Web Services for an introduction to HTML.
You can use a plain-text editor to create HTML files (or a word processor, being sure to save in plain-text or ASCII text mode). There are also numerous software packages which assist in developing HTML, such as Netscape Gold.
Even simple use of Chime requires that you write HTML files which can be viewed in Netscape 3.0 and served from your web server or viewed locally. (Internet Explorer does not provide full support for plug-ins.)
When you are curious how someone else used HTML to get a particular effect, use your browser's View, Source menu to see how they did it.
To find out more about HTML, press your web browser's Help button and look for a topic such as How to create web services. Also, your local library or bookstores have good introductions to HTML.
