• Fixed width width: 17em
• html { font-size: 62.5% }? — Why? What for? Then, font sizes are increased to 1.5em on an inner <div>! Again, what was the point in that?
• Finally, the site doesn't know whether its address is accessify.com or www.accessify.com.

• Font shenan­igans
• Absolute-​sized layout
• Dupli­cate pages
• Exces­sive page width

They've actually done some important things right, but the points above really bug me!
