read post https://stackoverflow.com/a/19688466/1663572 , related link http://abduzeedo.com/ios7-frosted-glass-effect-html-5-and-javascript

the solution uses steps.

  1. render html
  2. duplicate content area , convert canvas.
  3. move canvas header part
  4. sync scroll of content canvas in header

down on page example (the narrow one). there missing image or else , bit spilled try scrolling. i'm not sure frequency of changes of content mentioning. causing serious performance issues. try it.
