CSS slides

I read about the technology of CSS-slides, was shocked. How everything is elegant, and without scripts!
I liked the idea and I started making my own bike. Sometimes it is necessary to display a set of consecutive slides (something like a presentation).
After some experiments came to a very simple solution. I will be brief, everything is stated in a simple presentation .
UPD: Unfortunately, according to reports from the fields, it became known that in the Opera it does not work :-(.
I checked it myself in FF, IE, Safari for Windows ...
