An HTML document is simply a text file with a bunch of commands that will cause text and images to be manipulated in certain ways when you open it in a web browser. The web browser translates your text into a visually-appealling document.
To start making web pages, you need 2 things:
a) A Text Editor (such as Notepad on the PC and SimpleText on a Mac)
b) A Web Browser (such as Netscape or Internet Explorer)
To get started, create a new document in your text editor and begin creating your web page with all the various commands and tags, which will be explained later. Examples and Tutorials for this are found in the learnX.html files.
When you wish to view your web page, SAVE the file as "[Name of File].html" by doing a File, Save. Then open your web browser and go to File...Open and then track down the file and click open.
