[css-snappoints][css-scrollsnap] Mandatory snap-points, and voluntarily unreachable content

Here's just a use case I had in mind, which I think might be worth
considering in regards with the various snap-points options.

 

The use case is a slide-deck-like UA where one slide is visible at a time.
Each slide has an image background in connection with the content, here a
fiction about some forest and the four seasons. Backgrounds on consecutive
slides are transitioned using a cross-fade but these cross-fades happen
outside the interesting content, the "pages" of the slide-deck.

 



Figure 1: what the user would see if two panes where visible at once

 

 



Figure 2: What the user will actually see (dark green viewport)

 

The intent is that the user can see the cross-fade background section when
scrolling, but should only snap to the beginning of a page when moving using
arrow keys or just when the scroll ends, as the margin are not meant to be
readable.

 

Is that kind of experience possible to achieve under any of the
currently-proposed options?

 

Best regards,

Francois
