HTML writing guides are commercially available in bookstores; however, many are on line. You can find on line help for every level of web page development, from elementary to very advanced. Here are a few that I have found to be useful:

PBS - Creating Your Own Homepage
http://www.pbs.org/uti/guide/html.html

PBS has put together a site that has information about every aspect of web page design. This is an excellent way to learn what is available on the web to help you learn to make web pages.

Web 101
http://www.hotwired.com/web101/

A very nice introduction to the Internet, including history and definitions of terms. The links on this page will take you through basic information,  " . . . articles, cheat sheets, and tours that start from the beginning and explain what the Net is, what you can do with it, and how it works."

whatis.com
http://whatis.com/

"whatis® is a knowledge exploration tool about information technology,
especially about the Internet and computers. It contains over 1,500 individual encyclopedic definition/topics and a number of quick-reference pages. The topics contain over 5,000 hyperlinked cross-references and over 3,000 links to others sites for further information." 

World Wide Web FAQ
http://www.boutell.com/faq/oldfaq/index.html

This is another good starting place for those who are new to the internet. The site includes an introduction to the World Wide Web with definitions of most of the jargon you'll see when you browse the web. It has information on where to get web browsers and how to use them. Also included are guides to authoring web pages, creating images, and using programming on a web site.

NCSA--A Beginner's Guide to HTML
http://ww w.ncsa.uiuc.edu/General/Internet/WWW/HTMLPrimerAll.html

This is probably the definitive guide to writing HTML. The link I provided will take you to a page that has the entire manual on it, so it takes awhile to load. If you want to see the document in pieces (faster loading), go here: 

http://ww w.ncsa.uiuc.edu/General/Internet/WWW/HTMLPrimerP1.html

Links to all the variations of this guide are at the top of each page. Be sure to check out the links to other helpful sites listed at the end of the document. 

TIP: you can save a copy of the manual on your hard drive so that you can look at it anytime without having to be on line. If you are using a version of Netscape that has the editor built in, click File on the menu bar and select Edit Page. When the page finishes loading, click File and select Save As. Give the page a filename, such as: nscaguide.html. Open the page from your where you saved it on your hard drive into Netscape and add it to your bookmarks. 

If you aren't using Netscape, or if your version doesn't include the editor, do this:

• Click View on the menu bar and select View Page Source (or View Source, depending on the browser you are using).
• Now click Edit on the menu bar and choose Select All.
• Click Edit again and select Copy.
• Choose Edit and Paste in any word processor.
• When you save it, save it as a text file.
• Give it a name that ends with .html or .htm.

Now you can open this page in your browser, and all the links should still work.

As a last resort you can select all the text and paste into a word processor document for later reading just by selecting Edit from the menu bar and choosing Select All. Then select Edit again and choose Copy. In you word processor choose Edit and Paste. The disadvantage of this last way to save the document is that none of the page's hyperlinks will work. 

How do they do that with HTML?
http://www.nashville.net/~car l/htmlguide/index.html

This is a good starting point for learning some of the extended features of HTML. It is a pointer to pages that have advanced information on how to make your web page look like some of the commercial pages you see.
