where do the settings <h1> and so on get set
I am trying to set the font size in the page_postdate to a smaller font size I think I am doing this the wright way. Help
$string = $string . "<br><b><a href=\"";
if ($section_dir != "") {
$string = $string
. $section_dir . "/";
}

$string = $string . "item.php?id=". $id . "\">" . $title . "</a>" . "</b></br><br><h1>$page_postdate<b> to </b> $page_expiredate</h1></br>  \n";
}

One possibility global via CSS (cascade Style Sheets)

<html>
<head>
<title>Title</title>
<style type="text/css">
<!--
  h1 {font-size: 12pt;} 
-->
</style>
</head>
<body>
<h1>hello</h1>

</body>
</html>

another possibility direct

...<h1><small>$page_postdate<b> to </b> $page_expiredate</small></h1>...

and lot of other possibilities ...

hes right, best thing to do is make a gigantic css file for the whole site and have your common header(if you have one) link to it. i think every html tag can have styles, by a few methods:

<tag id="id" or
<tag class="class" or
<tag style="style:value"

so to setup all h1's the same or just make a general type you can do this:

and use <h1> (if using the first style ) or <h1 class=9> if using the 2nd one
