Here's the basic format to follow and you just plug
in whatever you want to use.

Here's the basic format:

TAG {definition; definition; definition}

Here's what a line defining the style for the <H2> tag looks like:

H2 {font-size: 16pt; font-style: italic; font-family: arial}

NOTICE! Here's a few things I'd like to point out:

• Notice the symbol before the definition is a { not a ( or a ].

• Notice the spaces! You don't need to leave them, but it helps you to be
  more able to read your style sheets later. Don't forget the semi-colons between each definition.

• Notice that each definition is separated by a semi-colon, but each definition contains a colon.
  You can use many definitions. You can use many Style Sheet commands to affect the same H2
  tag, if you want. Just remember to separate each definition by a semi-colon.

Which HTML Tags Can I Define?

As far as I know, you can define any HTML tag. Now, some definitions won't work with some tags.  For example, a font definition obviously won't work with an HR tag.

I see style sheets using these following tags the most:

• H1 through H6
• P
• BODY
• A:link (That denotes the unvisited link)
• A:visited (That denotes the visited link)
• A:hover (That denotes the state of a moused-over link)
• DIV (That denotes a division of the page)
