This is a .txt file. As you can see the browser
just prints out whatever is here. This  is close 
to simply using a typewriter to compose a WWW
page and it works pretty well. Actually, some
great pages have been published this way.

But it is so easy to markup a page like this with
hypertext markup language, that most people much
prefer the extra work.

The simplest markups are <p> for paragraph, <br>
for forcing a new line, <hr> for a hard rule,
<center> to center text and pictures, <h1> 
through <h7> for headers, <pre> for preformatted
text, etc. By the way the negative markup is
simple: </center> says not to center anymore,
</h1> says end of the header, and so on.

Note that this page looks like the .txt example,
which I copied but I wanted to be able to link
you to my CS HTML resource.
I also recommend my computer science page to
you for future browsing....
