Em Layout with max-width

If you click ⌘ + [Mac] or Ctrl + [Windows] a few times, the wrapper will expand. Once the width reaches 94% of the viewport, only the text will continue to resize.

#wrapper {
    background: #d4d4cd;
    width: 46em;
    max-width: 94%;
    margin: 1em auto;
    padding: 1em;
}

Back to Fluid, Elastic, Fantastic!
