I assume you are referring to the CSS solution? Yes, as I already stated in my reply, you won't get the animation using CSS. However, it is a reasonably close approximation for those who don't want to bother with JS for whatever reason.

Edit:

Could you link to an example of the file pages? If you are using Tabview for those, you need to add more CSS as Tabview uses different classes from the "built-in" tabs.
