The Basic Structure of a Web Document
HTML is an easy to understand language that is used to create Web pages. HTML (Hyper Text Markup Language) is written using tags which are American-English words or letters enclosed in the lesser than and greater than symbols on your keyboard. It's important to remember that almost all tags like the <p> tag which is the tag that 
denotes a paragraph must be used with a corresponding closing tag. The closing tag for <p> is </p> which tells the Web browser that this is where this paragraph ends. All HTML documents (Web pages in in their coded form, which we are discussing here, are called HTML documents) must begin with <html>and end with </html> just like in the example code below. All HTML documents are divided into two sections: the head section and the body section. The head section of an HTML document begins with <head> and ends with </head> and the body section begins with <body> and end is with </body>. The head always rests on top of the body in an HTML document. Don't worry. We'll talk more about the head and body of HTML documents later on.
The following is a complete HTML document that will open as a Web page in any Web browser:
Click it and it will open in Internet Explorer or whatever you use as your default Web browser. 
Here's what it looks like in my default browser - FireFox. It will probably look slightly different in your browser whether your default browser is FireFox, like mine, or Microsoft's Internet Explorer or any number of terrific browsers that are free to download and use like Google's browser named Chrome. The important thing for now is to understand the basic structure of the above code. Notice how everything is wrapped between the html opening and closing tags. Notice that the opening and closing head tags contain nothing for now but the title of our Web page. And notice how the opening and closing body tags contain all of the content of our Web page. But the Web page, itself, looks a little cheesey, doesn't it? Actually, it looks a lot cheesey. So let's dress it up some. We'll add some stuff to the basic code we started with. Notice that the new code below is the same as the above code but we've just added some stuff to it. 
How were these changes made? First of all, we added a style to the body tag that caused the background of the entire page to turn from white (the default background color) to orange. The body section of an HTML document is the only part of the document that shows when the page is displayed. The head section is used mostly to give the browser more information about how to display the page. The only thing in the head section of the document that shows up on your Web page is the information between the title tag and the closing title tag. Your title will appear on the browser title bar. The second change we made to the HTML code is to apply a style to our paragraph tag that gives the paragraph its own background color, in this case - black. That style also caused the text to be colored red and moved to the center of the page. Don't worry if the styles codes look a little confusing. We'll talk more about styles in the next post. Finally, we placed all six HTML heading tags on the page. You might use the h1 tag for your most important heading and then one or two of the smaller heading tags thereafter. When I made this page, I used the h2 tag to give it a title at the top of the page which is How to Create a Web Page. Just beneath that, I used an h3 tag to display a sub-title - The Basic Structure of a Web Document.
I intend to edit it and add to it from time to time. In the meantime, if you have any ideas about how I could enhance the content of this page, please email me about it.
