You don't need to purchase any fancy Web page authoring software; instead, you can learn to write Web pages using a plain text editor. This has the advantage of giving you full control over your Web pages, and the knowledge that it will be viewable by any Web browser because you can omit any software- or browser-specific "tags." You can create your first Web page this way in a minimum of time, and add to your skills as you continue.
All Web pages are based on "HTML" (HyperText markup language). Click on any of the following links to get your feet wet. Go ahead and jump in---be brave!
