HTML table pure CSS fixed header

This is a, slightly hackish, pure CSS implementation of a fixed table header. It is implemented in HTML5 and CSS3 and is tested in FX 25, Chrome 31 and IE 10.

HTML

<script src="http://code.jquery.com/jquery-2.1.4.min.js"></script>
<script src="https://code.jquery.com/jquery-2.1.4.min.js"></script>

<p><input type="radio" class="rad" id="visitor" name="travelertype" /> Value</p>

<p><input type="radio" class="rad" id="ucstudent" name="travelertype"/>
    UC Student</p>

<p><input type="radio" class="rad" id="ucemployee" name="travelertype"/>
    UC Employee</p>

CSS
