<h2>CSS Comments</h2>
<p>Comments are used to explain your code, and may help you when
you edit the source code at a later date. A comment will be ignored by
browsers. A CSS comment begins with "/*", and ends with "*/", like this:</p>
<table width="100%" border="1" class="ex" cellspacing="0"><tr><td>
<pre>/* This is a comment */
p
{
text-align: center;
/* This is another comment */
color: black;
font-family: arial
}</pre>
