I want the collapse behavior of my container block

Question

I spent hours searching the solution of this issue. All i found is the inverse of the desired behavior. As the title says, what i want is that my '' container collapse and get no height when it have the property 'position:fixed' This is the code block.

<div style="position:fixed;right:0;bottom:0">
    <div style="float:left">First DIV</div>
    <div style="float:left">Second DIV</div>
</div>

Thank you

I think i have the response of the problem. I put a middle container between the main container and the elements that have an absolute position. The code became :

<div id="main_container">
  <div id="middle_container">
    <div class="element">First DIV</div>
    <div class="element">Second DIV</div>
    ...
  </div>
</div>


#main_container{
position : fixed;
right : 0;
bottom : 0;
}
#middle_container{
position : absolute;
right : 0;
bottom: 0;
}
.element{
float : left;
}

Thanks all for your responses. And sorry for the problem description clarity.
