For what it's worth, the "scroll-snap" property was something I was just 
going to say it was mandatory to get Tab's proposal working. Indeed, if you 
want to use animations as a scroll behavior for slides or an image carousel, 
you need to have snap points in order to get it to work. Florian spotted 
another sample where you want either to return to 0% to go up to 100%. So, I 
was going to argue that we had to standardize something like that first. 
Seems like I don't need to argue that anymore (I was wise to wait, I just 
spared a bunch of minutes of my time :D) and I can be happy with just saying 

BTW, I didn't knew the property existed at all in IE10, so that's maybe an 
under-advertized property. I did make one or two Windows 8 app in HTML/CSS, 
I would have loved to know this property existed. Some new homework for your 
IEBlog redactors ?-)

However, that doesn't mean Tab's proposal isn't worth it. To be honest, I 
see quite a number of places (slides transitions, carousel, animated 
cartoons ...) where it's critical for performance reasons. But, for all 
those cases, we need snap points first to get something that works properly. 
So, let's try to get snap points working first, and let's keep Tab's 
proposal for later. Anyway, I guess we're probably going to wait for 
WebAnims to specify better the concept of Timeline before introducing it in
