I was validating the markup on my website and noticed the <link> tag outputted for the plugin is invalid.
Specifically, there is an unnecessary </style> tag at the end of the scriputrizer.css declaration.
Currently:
<link rel="stylesheet" type="text/css" media="screen" href="scripturizer.css"/></style>
Should be:
<link rel="stylesheet" type="text/css" media="screen" href="scripturizer.css"/>
