Comment in HTML:
The comment tag is used to insert a comment in the HTML source code. A comment will be ignored by the browser. You can use comments to explain your code, which can help you when you edit the source code at a later date.

Note that you need an exclamation point after the opening bracket, but not before the closing bracket.

File Extension........

HTM or HTML Extension?
When you save an HTML file, you can use either the .htm or the .html extension. We have used .htm in our examples. It might be a bad habit inherited from the past when some of the commonly used software only allowed three letter extensions.
With newer software we think it will be perfectly safe to use .html.

Introduction to HTML..........

What is an HTML File?
1.HTML stands for Hyper Text Markup Language
2.An HTML file is a text file containing small markup tags
3.The markup tags tell the Web browser how to display the page
4.An HTML file must have an htm or html file extension
5.An HTML file can be created using a simple text editor

Do You Want to Try It?
If you are running Windows, start Notepad.
If you are on a Mac, start SimpleText.
In OSX start TextEdit and change the following preferences: Open the the "Format" menu and select "Plain text" instead of "Rich text". Then open the "Preferences" window under the "Text Edit" menu and select "Ignore rich text commands in HTML files". Your HTML code will probably not work if you do not change the preferences above!
Type in the following text:

Save the file as "mypage.htm".

Start your Internet browser. Select "Open" (or "Open Page") in the File menu of your browser. A dialog box will appear. Select "Browse" (or "Choose File") and locate the HTML file you just created - "mypage.htm" - select it and click "Open". Now you should see an address in the dialog box, for example "C:\MyDocuments\mypage.htm". Click OK, and the browser will display the page.
