- Made the width and height of the smart wizard responsive. It now scales depending on window size. You can optionally override this with static values using your own CSS for container height/width.
- Using border-box to accomodate responsive 100% width. Otherwise, padding overflows outside container.
- Removed unecessary overflow-x and overflow-y css since width and height autoscale.
- Added border-radius property where it was missing. Necessary for browsers that don't use moz-border-radius and webkit-border-radius.
