CSS3 Transitions have nothing (or at least, not much) to do with the kind of 
"visual transitions" you're requesting, apart from their name.
CSS3 Transitions are "property transition": the top property was equal to 
0px before the transition and will move smoothly to 5px during a certain 
timespan instead of being immediatly set to 5px when changed: a "transition" 
is being applied to generate intermediate values for the property.

At this time, there's no "visual" property in CSS, so you can't 
transitionate the visual.

However, while Visual Transitions are not available in CSS today, they are 
part of the DHTML "standards" : 
http://msdn.microsoft.com/en-us/library/ms532847(v=VS.85).aspx
With Visual Transitions, you start from a certain visual and you end up with 
another visual. Instead of replacing one visual by another, a "transition" 
is being applied to generate intermediate frames. The simplest visual 
transition is the "fading". The "fading" behavior is the closest of the 
current CSS definition of transitions, because it's a sort of interpolation. 
More complex visual transitions requires a completely new property.

François

Subject: document transition effect

Hi,
CSS3 Transition defines how transitions are done over time, but only for
properties inside the document.
I was wondering if the same could be done for transitions between
documents (like fade, display once complete, dissolve, etc...) could a
pseudo-property be defined for that (if it is not already the case and I
missed it).
Thanks,
