There seem to be a lot of HTML questions being asked these days, so I thought I would try to help out.
Here is a list of html tags. The word in the center is an example of what the tag does.
Each tag begins with < (left angle bracket) and ends with > (right angle bracket).
Style Tags modify the way your text looks. NOTE: In general, all HTML commands will take the form:
<COMMAND> text </COMMAND>.

• <B>bold</B>
• <I>italics</I>
• <STRONG>strong</STRONG>
• <BLINK>blink</BLINK>
• <CODE>code</CODE>
• <EM>emphasize</EM>
• <ADDRESS>
  address
  </ADDRESS>
• <CITE>citation</CITE>
• <SAMP>sample</SAMP>
• <KBD>keyboard entry</KBD>
• <TT>teletype</TT>
• <BIG>big print</BIG>
• <SMALL>small print</SMALL>
• <SUB>_subscript</SUB>
• <SUP>^superscript</SUP>
• <STRIKE>strikeout</STRIKE>
• <PRE>

Heading Tags are very similar to style tags. Headings come in six sizes, 1-6. 1 is the largest. 6 is smallest. The heading tag also includes an implicit <BR> at the beginning and end. The format for the heading tags is <H#> with # being a number 1-6, and they look like this:

<H1>

This is a size 1 heading

</H1>

<H2>

This is a size 2 heading

</H2>

<H5>

This is a size 5 heading

LINKS

Links come in three basic varieties: links to other files, links to the same file and links to pictures.
To link to another file on another server, use
<A HREF="http://server/path/filename.html"> anchor text </A>. This is called absolute linking. The tag is called an anchor.

Example: <A HREF="http://www.disney.com"> The Walt Disney Home Page </A>

To link to another file on the same server, use <A HREF="path/filename.html"> anchor text </A>. That is called relative linking.

Example: <A HREF="../auction/Auction.html"> The Auction Block</A>
