Class attribute as a jquery selector when css class already exists
<p>I understand that selecting by the <code>class</code> attribute in jquery is one of the most performant ways of selecting elements. We apply the <code>class</code> attribute on all elements to represent the CSS style. I'd like to select a subset of these elements using jquery class selector. </p>

<p>So, should I be applying multiple styles to the element - one to represent the css style and the other on solely for jquery selection purposes?</p>
