SIMPLE HTML RULES:
1. <I'm a TAG>:
TAGS are commands that tell browsers what to do. They are bounded by < brackets >.
TAGS are case insensitive, which means you may use <html>, <htML> or <HTML>.
2. <center> and <h1> are examples of BEGINNING TAGS and
</CENTER> and </H1> are examples of END TAGS.
The BEGINNING TAG turns the command on and the END TAG turns the command off.
You have to use both for most tags.3. File names are case sensitive:
While TAGS are case insensitive, file names are case sensitive, which means you should always use the exact file name such as: clouds.gif (so "clouds.GIF" or "CLOUDS.GIF" will not work!).
4. Most HTML files end with .htm or .html
Most browsers will not be able to read the file without one of these two endings.
