A robust fluid (middle column any size) three-column layout from Stylin' with CSS using min-width and max-width

• If page size gets too large, it centres it using CSS max properties
• Uses background images to make outer columns full length
• Uses Aslett clearing to get the footer right

  .clearfix:after {
      content: "."; 
      display: block; 
      height: 0; 
      clear: both; 
      visibility: hidden;
  }
  

  Adds a paragraph containing a full stop that is zero height so invisible!
• Uses a Javascript to get round IE6 bugs
