resizing browser window

[Angelo Chen]

Hi,

I have this:

<div class="row>
  <div class="span6" id='left'>
   </div>

   <div class="span6" id='right'>
   </div>

</div>

when browser window resizes, the 'left' move to the left, and leaving
a big space in the center, is there a way to tell 'left' not to move
to the left, but toward the right, so no big space in the center?

Thanks,

Angelo
