save the following, in test.php
<style type="text/css">
<!--
.content_gray {
font-size: 11px;
font-family: Arial;
color: #999999;
font-weight: normal;
line-height: 2em;
}
</style>
<?
echo "<span class='content_gray'>Individually Tailored IT Services</span>";
?>
the top section is CSS, i have included this code to be in the same file.
the php is the 2nd part, as you can see in the echo command which is php, there is just plain general HTML, but as you will notice, the text is formated by the use of CSS
When CSS becomes complex or just to have things all in there own place, the CSS code goes in its own file, and you refference to that file like you did above.
