Very neat, I checked out the other stuff you've got on there and it's pretty sweet.<p>Seems like a lot of people have missed the point that this is just a hack to see if a light box in JUST CSS and HTML could be made. Because theres no JS or actual logic, this demo just leverages the browser to maintain the state. It's a necessary side effect that the back buttons behave this way, and it <i>could</i> be coded to behave differently, but that would defeat the purpose of the exercise.
