Force container to stay in exact positions

Hello, I am trying to make it so the container on this page http://s72956.gridserver.com/dev/toggle.html# will always stay at a certain width no matter how you resize the page is there any easy way of doing this.

From stackoverflow newhen

• If you specify a width of a block element explicitly, it will stay at that width.

  <div style="width:300px">
     ...
  </div>
  

  Will remain 300 pixels wide not matter what. You might however want to specify the width in css rather an inline like I did here.

  newhen : even with that it still moves.

  newhen : try moving your browser.
