Stylesheets can be used to modify the default formatting of tags:
 Tags
provide much of the formatting in HTML. And they impose their
default formatting on your documents. Stylesheets can modify
that default formatting.  Example
1: <tt></tt>
|
The default formatting for the <tt></tt>
tag is too small to read, and its default font is not always displayed as monotype.
 <tt> default</tt>
The Library stylesheet redefines the size and font for the <tt></tt>
tag.
<tt> modified</tt>
|
This is how the <tt></tt> tag is redefined in the Research Guides stylesheet.
tt {
font-family: Courier, monotype;
font-size:
12px;
}
|
Example
2: <h2></h2>
|
Here is the default formatting for the
<h2></h2> tag:
<h2>default<h2>
The Library stylesheet redefines the color and font of the <h2></h2>
tag:
<h2>modified</h2>
|
This is how the <h2></h2>
tag is redefined in the Research Guides stylesheet.
h2
{
font-family: Arial, Helvetica, sans-serif;
color: #990000;
}

An interactive area on the W3C site lets you play with stylesheet rules. (It deals almost exclusively with modifying tags.)
