title: CSS set width to fill % of remaining area
body: <p>Sorry for the slightly rubbish title.  I could not think how to describe this one better.</p>
  
  <p>I am trying to implement the Google Friend Connect members gadget on my site, (just got into the scheme and want to put it in without a major redesign, at least for testing sake).</p>
  
  <p>My problem is as follows:</p>
  
  <p>I have a container div that has a width of 90% of the main page (body).  Inside this I am floating a div to the right and setting its width to 300px and putting the google gadget inside it.  What I would like is to be able to have a div fill 95% of the space remaining to the left of the google gadget div. </p>
  
  <p>I don't know if it is possible to be able to mix px and % with divs and widths.  </p>
  
  <p>I hope this makes sense.</p>
  
  <p>Thanks</p>
