1. Creating Your First HTML Document

You are about to embark on a journey that will transform you from a mere Internet Surfer of the Web to an Internet Author of Multimedia!

Objectives

After this lesson you will be able to:

Identify the meaning and purpose of HTML tags.
Open up a workspace for creating new HTML documents.
Use a text editor to create the basic HTML structure for any web page.
Insert non-displayed comments into your HTML files.
Open your document within your web browser to see how it is displayed.

Lesson

Now that you know what HTML is, let's start using it.

(Quick quiz -- what do those letters stand for? If you read the previous lesson you would know!).

What are HTML tags?

When a web browser displays a page such as the one you are reading now, it reads from a plain text file, and looks for special codes or "tags" that are marked by the < and > signs. The general format for a HTML tag is:

     <tag_name>string of text</tag_name>

As an example, the title for this section uses a header tag:

     <h3>What are HTML tags?</h3>

This tag tells a web browser to display the text What are HTML tags? in the style of header level 3 (We'll learn more about these tags later). HTML tags may tell a web browser to bold the text, italicize it, make it into a header, or make it be a hypertext link to another web page. It is important to note that the ending tag,

    </tag_name>

contains the "/" slash character. This "/" slash tells a web browser to stop tagging the text. Many HTML tags are paired this way. If you forget the slash, a web browser will continue the tag for the rest of the text in your document, producing undesirable results (as an experiment you may want to try this later).

NOTE: A web browser does not care if you use upper or lower case. For example, <h3>...</h3> is no different from <H3>...</H3>

Unlike computer programming, if you make a typographical error in HTML you will not get a "bomb" or "crash" the system; your web page will simply look, well... wrong. It is quick and easy to go inside the HTML and make the changes.

Your browser has a small but open vocabulary! An interesting aspect of HTML is that if the browser does not know what to do with a given tag, it will ignore it! For example, in this document you are viewing, the header tag for this section really looks like this:

    <wiggle><h3>What are HTML tags?</h3></wiggle>

but since your browser probably does not support a <wiggle> tag (I made it up, perhaps in the future it could cause the text to wave across the screen?), it proceeds with what it knows how to do. If I was programming a new web browser, I might decided to add the functionality for the <wiggle> tag into my software.

Opening Up Your Workspace

To complete the lessons in this tutorial, you should create a second web window (this allows you to keep this window with the lesson instructions and one window as your "workspace"), plus open your text editor application in a third window.

NOTE: This is a good place to remind you that we will provide directions that are somewhat general as the menu names and file names can differ depending on which web browser you are using.

So you will want to be pretty comfortable jumping between different applications and windows on your computer. Another option is to print out the lesson instructions (but we really do not want to promote tree carnage).

Here are the steps for setting up your workspace:

From the File menu of your web browser, select New Window or New Web Browser. A second web window should appear. Think of the first window as your "textbook" and the second clone window as your "workspace" for completing the HTML lessons.

NOTE: The only reason to have two windows here is so that you can read the instructions for the lessons and also view your working document. You could also bookmark this web page and jump back here via your Go or History menu.
Next, you need to jump out of the web browser and open your text editor program.

NOTE: You will need to move back and forth between the different windows to complete these lessons. This can be a challenge depending on the size of your monitor. You may choose to resize the three windows so that they all fit on your screen or layer your windows so you can click on any of them to bring it to the front.
If you are using a word processor program to create your HTML, be sure to save in plain text (or ASCII) format.

If you are just starting out, we most STRONGLY recommend that you use the simplest text editor available -- SimpleText or TeachText for the Macintosh or the Windows NotePad. Why not use those nifty HTML editors? It is sound instructional design that you first learn the concepts and THEN look for shortcuts or helpers that make the work less tedious.

Also, it will help you if you first create a new directory/folder on your computer that will be your work area. You can call it workarea or myspace or whatever you like; just make sure that you keep all of the files you create in this one area. It will make your life simpler... well, at least while working on this tutorial!

Creating Your HTML Document

An HTML document contains two distinct parts, the head and the body. The head contains information about the document that is not displayed on the screen. The body then contains everything else that is displayed as part of the web page.

The basic structure then of any HTML page is:


  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">
  <html>
  <head>
  <!-- header info used to contain extra information about
       this document, not displayed on the page -->
  </head>

  <body>
  
  <!-- all the HTML for display -->
          :      :
          :      :
          :      :
  </body>
  </html>

The very first line:

  <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">

is not technically required, but is a code that tells the browser what version of HTML the current page is written for. For more information, see the W3C Reference Specification.

Enclose all HTML work within <html>...</html> tags. Inside is first your <head>...</head> and then the <body>...</body>. Your web pages may display fine on most computers without any of these tags. However by using them, your web pages will be fully compliant with International HTML standards and ensure compatibility with future web browsers.

It's good habit, like brushing your teeth.

Also note the comment tags enclosed by . The text between the tags are NOT displayed in the web page but are there to put information that might be of use to yourself or anyone else that might look at the HTML behind the web page. When your web pages get complicated (like you will see when we get into tables, frames, and other fun stuff about 20 lessons from now!), the comments will be very helpful when you need to update a page you may have created long ago.

Here are the steps for creating your first HTML file. Are you ready?

If it is not open already, launch your text editor program.
Go to the text editor window.
Enter the following text (you do not have to press RETURN at the end of each line; the web browser will word wrap all text):
```
     <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN">
     <html>
     <head>
     <title>Volcano Web</title>
     </head>
     
     <body>
     In this lesson you will use the Internet to research 
     information on volcanoes and then write a report on 
     your results.
     </body>
     </html>
```
NOTE: Look where the <title>...</title> tag is located. It is in the <head>...</head> portion and thus will not be visible on the screen. What does it do? The <title> tag is used to uniquely identify each document and is also displayed in the title bar of the browser window.
In lesson 3 you will learn how to add a title that will appear directly on your web page.
Also note that we have inserted a comment tag that lists the name of the author and the date the document was created. You could write anything in between the comment tags but it is only visible when you look at the source HTML for a web page.
Save the document as a file called "Volc.html" and keep it in the "work area" folder/directory you set up for this tutorial. Also, if you are using a word processor program to create your HTML, be sure to save in plain text (or ASCII) format.
NOTE: For Windows 3.1 users, you must save all of your HTML files with names that end in .HTM, so in this case your file should be VOLC.HTM. Do not worry! Your web browser is smart enough to know that a file that has a name that ends in .HTM is an HTML file.
You can create files with names like VOLC.HTML if you use Windows95 or Windows NT.
By using this file name extension, a web browser will know to read these text files as HTML and properly display the web page.

Displaying Your Document in a Web Browser

Return to the web browser window you are using for your work space. (If you do not have a second browser window open yet, select New Window or New Browser from the File window.)
Select Open File... from the File menu.
Use the dialog box to find and open the file you created, "Volc.html"
You should now see in the title bar of the workspace window the text "Volcano Web" and in the web page below, the one sentence of <body> text you wrote, "In this lesson..."

Check Your Work

Compare your document with a sample of how this document should appear. After viewing the sample, use the back button on your web browser to return to this page.

If your document was different from the sample, review the text you entered in the text editor.

The most common mistake is, "I cannot see the title!" You shouldn't! The text within the <title>...</title> tag is NOT displayed on the web page; you should see it in the titlebar of the web browser window.

Independent Practice

Think of a topic for your own web page. Now create your own HTML text file that includes a <title> tag and a few introductory sentences. Save the HTML file and reload it in your web browser. You might want to create a different folder/directory for this file so you do not get it mixed up with all of the volcano pages you will create for this tutorial.

Keep this file handy as you will add to it in later lessons.

Coming Next....

Your first web page is done!

But, to be honest, it is pretty short and not very exciting! In the next lesson you will modify and update your HTML document.
