Tricky CSS Layout

So I am making a website with quite a problematic layout. There are four corner images TL, TR, BL and BR indicated by black blocks. The dark orange area is the main content (to a width of 960px), with the outside area denoted by the green arrow as the browser window. See diagram:

Diagram http://dotcafedesigns.com/stackoverflow/problem.gif

The top image represents the site at its narrowest possible - it shouldn't be allowed to be narrower than this (960px) if it is larger than the defined area there should be no scrollbars. The bottom two images represent different widths of browser.

The bottom left and right black blocks (images) should be at the bottom left and right of the screen at all times, unless the width falls to 960px, in which case the BL and BR images should poke into the main area slightly. If the site is shrunk to, say 200px, the BR image should not still be poking in the right corner.

At this point I don't really care about it working exactly in IE6 (I can get it roughly working) but I can't even figure out how to do it fully without Javascript or extremely experimental CSS. Currently I am using absolutely positioned div's which sort of work, but don't work quite right.

I think I'd be willing to accept a bit of JS if there is no other way but I'd rather not.

Answer very appreciated!

No need for Javascript. At least in most modern browsers. Using simple positioning and one @media query I pulled it off:

<head>
  <style type="text/css" media="screen">
    body {
      margin: 0;
      padding: 0;
      font-family: sans-serif;
      background: orange;
      text-align: center;
      color: black;
      overflow-x: hidden;
    }
    #content {
      width: 960px;
      margin: 0 auto;
      padding: 20px 0;
      min-height: 800px;
      background: #cc6600;
      z-index: 0;
    }
    .image {
      background: black;
      color: white;
      height: 60px;
      width: 100px;
      padding: 20px 0;
      z-index: 1;
      opacity: .95;
    }
    #top {
      width: 960px;
      margin: 0 auto;
      position: relative;
      overflow: visible;
    }
    #top .image {
      position: absolute;
    }
    #top .left {
      left: -80px;
    }
    #top .right {
      right: -80px;
    }
    #bottom {
      position: fixed;
      bottom: 0;
      width: 100%;
      height: 100px;
    }
    #bottom .image {
      position: absolute;
    }
    #bottom .left {
      left: 0;
    }
    #bottom .right {
      right: 0;
    }

    @media all and (max-width:1120px) {

      #container {
        width: 960px;
        margin: 0 auto;
        position: relative;
        overflow: visible;
      }
      #bottom .left {
        left: -80px;
      }
      #bottom .right {
        right: -80px;
      }    

    }
  </style>
</head>
<body>
  <div id="top">
    <div class="left image">left image</div>
    <div class="right image">right image</div>    
  </div>
  <div id="content">
    content
  </div>
  <div id="bottom">
    <div id="container">
      <div class="left image">left image</div>
      <div class="right image">right image</div>
    </div>
  </div>
</body>

That may fall under your description of "extremely experimental CSS", but I think you'd be surprised by how much support it does have, and how easy it would be to bootstrap that with a touch of JS - simply check browser width on re-size and add the extra CSS when the width falls under 1120px.

Something like this? You may replace the JavaScript code with similar JQuery code if you like, just wanted to give the idea how this could work.

<html>
<head>
  <title>....</title>

  <style type="text/css">
  html
  { height: 100%; margin: 0; background: white; }
  body
  { height: 100%; width: 960px; margin: 0 auto; background: gray; overflow: hidden; }
  #main
  { margin: 0px; padding: 5px 20px; position: relative; }

  #headLeft
  { position: absolute; top: 0px; left: -80px;
    width: 100px; height: 35px; background: green; }
  #headRight
  { position: absolute; top: 0px; right: -80px;
    width: 100px; height: 35px; background: green; }
  #footLeft
  { position: absolute; bottom: 0px; left: 0px;
    width: 100px; height: 35px; background: green; }
  #footRight
  { position: absolute; bottom: 0px; right: 0px;
    width: 100px; height: 35px; background: green; }
  </style>

  <script type="text/javascript">
  function checkSize ( event )
  {
    var contentWidth = 960;
    var minOuterBoxSize = 60; // maximum 100-60=40 px will be displayed inside the main area

    if ( window.innerWidth - contentWidth < minOuterBoxSize * 2 )
    {
      var pos = ( ( minOuterBoxSize * 2 ) - window.innerWidth + contentWidth ) / 2;
      document.getElementById( 'footLeft' ).style.left = '-' + pos;
      document.getElementById( 'footRight' ).style.right = '-' + pos;
    }
    else
    {
      document.getElementById( 'footLeft' ).style.left = '0px';
      document.getElementById( 'footRight' ).style.right = '0px';
    }
  }
  </script>
</head>

<body onload="checkSize( event );" onresize="checkSize( event );">
 <div id="main">
  <div id="headLeft">TL</div>
  <div id="headRight">TR</div>

  <p>Normal content</p>
 </div>

 <div id="footLeft">BL</div>
 <div id="footRight">BR</div>
</body>
</html>
