can the width in css be selected dynamical with a variable
===

the code is :


    <div class="bar">
        <div class="percentage" style="width:16%; height: 59px;">This is 66% wide div</div>
    </div>

As you can see the width is 16 here....i need a way that it could be changed based on a variable like. I have a query which returns a certain vale. And the width must be that vale. how can i do that?
