[css] CSS: Auto resize div to fit container width

I have two <div>: left and contents. These two are inside wrapper div that has min-width:960px;. left has fixed width, but I want to make content flexible with min width of 700px and if screen is wider, stick it to the right bound of screen.

CSS:

#wrapper
{
    min-width:960px;
    margin-left:auto;
    margin-right:auto;
}
#left
{
    width:200px;
    float:left;
    background-color:antiquewhite;
    margin-left:10px;
}
#content
{
    min-width:700px;
    margin-left:10px;
    width:auto;
    float:left;
    background-color:AppWorkspace;
}

CSS auto-fit container between float:left & float:right divs solved my problem, thanks for your comments.

#left
{
    width:200px;
    float:left;
    background-color:antiquewhite;
    margin-left:10px;
}
#content
{
    overflow:hidden;
    margin-left:10px;
    background-color:AppWorkspace;
}

#wrapper
{
    min-width:960px;
    margin-left:auto;
    margin-right:auto;
    position-relative;
}
#left
{
    width:200px;
    position: absolute;
    background-color:antiquewhite;
    margin-left:10px;
    z-index: 2;
}
#content
{
    padding-left:210px;
    width:100%;
    background-color:AppWorkspace;
    position: relative;
    z-index: 1;
}

If you need the whitespace on the right of #left, then add a border-right: 10px solid #FFF; to #left and add 10px to the padding-left in #content

You could use css3 flexible box, it would go like this:

First your wrapper is wrapping a lot of things so you need a wrapper just for the 2 horizontal floated boxes:

 <div id="hor-box"> 
    <div id="left">
        left
      </div>
    <div id="content">
       content
    </div>
</div>

And your css3 should be:

#hor-box{   
  display: -webkit-box;
  display: -moz-box;
  display: box;

 -moz-box-orient: horizontal;
 box-orient: horizontal; 
 -webkit-box-orient: horizontal;

}  
#left   {
      width:200px;
      background-color:antiquewhite;
      margin-left:10px;

     -webkit-box-flex: 0;
     -moz-box-flex: 0;
     box-flex: 0;  
}  
#content   {
      min-width:700px;
      margin-left:10px;
      background-color:AppWorkspace;

     -webkit-box-flex: 1;
     -moz-box-flex: 1;
      box-flex: 1; 
}

I have updated your jsfiddle and here is CSS changes you need to do:

#content
{
    min-width:700px;
    margin-right: -210px;
    width:100%;
    float:left;
    background-color:AppWorkspace;
}
