no... classes are classes, rules are rules, selectors are selectors... 

I may be getting off course from what you really need, but
<style>
div {background-color: white;}
div.myClass {background-color: red;}
</style>


<div id="myDiv"></div>  will have background-color: white;

<div id="myDiv" class="myClass"></div> will have background-color: red;

<div id="myDiv" class="myClass" style="background-color: blue;"></div> will
have a class="myClass", but background-color: blue;
