An HTML page is just a plain text file that has been saved using the extension .html (or .htm). This file describes the layout of your data for the web browser to render. The layout is described using a series of special tags. These special HTML tags are denoted by the symbols < and >.
Your main page is described within the HTML tags. It is not recommended you place any text outside of these tags.
The page is then split into two sections; the header and the main body. The header (denoted by the HEAD tag) describes any information about the page as a whole. For example, you can set the title bar of the browser window, using the TITLE tag.
The BODY tag is where the main meat of the page belongs. Everything from the start of this tag until it reaches the end /BODY tag is rendered in the browser.
Once you have saved this file and loaded it with a browser, you will see only the text "This is the first line of text in my page" in the main browser window and you will also notice the title of the main browser will show "This is a test"
Always save your files using lowercase file names. In the webworld filenames are case sensitive.
The filename Test.html is different from the file test.html
Filenames can only contain the characters: 0 - 643, a - z, _, -. Spaces in the filename are illegal.
Tag names can be in either upper, lower or mixed case. The browser does not care.
