Introduction to HTML

What is an HTML File?

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

Do You Want to Try It?

Start the "Plain text" editor of your operating system (such as notepad for windows, kwrite for Linux, ...).

Note: It is very important to save the text as "Plain text" instead of "Rich text" because if you don't do this HTML codes probably won't work.

Type in the following text:

<html>
<head>
<title>Title of page</title>
</head>
<body>
This is my first homepage. <b>This text is bold</b>
</body>
</html>

Save the file as "mypage.htm".

Start your Internet browser. Select "Open" in the File menu of your browser. A dialog box will appear. Select "Browse" 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.

Example Explained

The first tag in your HTML document is <html>. This tag tells your browser that this is the start of an HTML document. The last tag in your document is </html>. This tag tells your browser that this is the end of the HTML document.

The text between the <head> tag and the </head> tag is header information. Header information is not displayed in the browser window.

The text between the <title> tags is the title of your document. The title is displayed in your browser's caption.

The text between the <body> tags is the text that will be displayed in your browser.

The text between the <b> and </b> tags will be displayed in a bold font.

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.

Note on HTML Editors

You can easily edit HTML files using a WYSIWYG (what you see is what you get) editor like FrontPage instead of writing your markup tags in a plain text file.

But if you want to be a skillful Web developer, we strongly recommend that you use a plain text editor to learn your primer HTML.

Frequently Asked Questions

Q: After I have edited an HTML file, I cannot view the result in my browser. Why?
A: Make sure that you have saved the file with a proper name and extension like "c:\mypage.htm". Also make sure that you use the same name when you open the file in your browser.
Q: I have tried to edit an HTML file but the changes don't show in the browser. Why?
A: The browser caches your pages so it doesn't have to read the same page twice. When you have changed a page, the browser doesn't know that. Use the browser's refresh/reload button to force the browser to read the edited page.
Q: What browser should I use?
A: You can do all the training with all of the common browsers, like Internet Explorer, Mozilla, Netscape, or Opera. However, some of the examples in our advanced classes require the latest versions of the browsers.
Q: Does my computer have to run Windows? What about a Linux?
A: You can do all your training on a non-Windows computer like a Linux. However, some of the examples in our advanced classes require a newer version of the browser.
