I really liked culytera's titlepage so I thought I would adopt it. However,
titlepage_start doesn't appear to work as advertised. I am probably missing a setting somewhere. This is the resultant HTML:
Code:
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Harmony and the Olympians by Lunar_Raider</title>
<style type="text/css">
body { background-color: #ffffff; }
.CI {
text-align:center;
margin-top:0px;
margin-bottom:0px;
padding:0px;
}
.center {text-align: center;}
.cover {text-align: center;}
.full {width: 100%; }
.quarter {width: 25%; }
.smcap {font-variant: small-caps;}
.u {text-decoration: underline;}
.bold {font-weight: bold;}
.big { font-size: larger; }
.small { font-size: smaller; }
</style>
</head>
<body class="fff_titlepage" style="font-size: 2.5vmax;">

<p>Harry starts reading a muggle series on a recommendation from Dudley. When Hermione sees he's taken an interest in reading, she immediately jumps to read the series alongside him. The two draw their own conclusions about their similarities with the series' two main leads, and it lends itself to a revelation for Harry.</p></div></div>
Note: I made a minor changes where my heading is <h1>${title} by ${author}
