An IBM website talking about rapid web development here mentioned a useful skeleton HTML. In the template, the script inclusion is inside body rather than head. Is it a good practice? Isn't it better to put any library inside head instead?
<html>
<head>
<title>Template</title>
<link href=css/bootstrap.min.css rel=stylesheet media=screen>
<link href=css/bootstrap-responsive.min.css rel=stylesheet>
</head>
<body>
<!-- The main HTML will go here -->
<script src=http://code.jquery.com/jquery.js></script>
<script src=js/bootstrap.min.js></script>
</body>
</html>
VS
<html>
<head>
<title>Template</title>
<link href=css/bootstrap.min.css rel=stylesheet media=screen>
<link href=css/bootstrap-responsive.min.css rel=stylesheet>
<script src=http://code.jquery.com/jquery.js></script>
<script src=js/bootstrap.min.js></script>
</head>
<body>
<!-- The main HTML will go here -->
</body>
</html>
