- A couple of
#jump-linksis all you need to make navigation for it, which you can make all nice and smooth with
Christian Schaefer has taken it a little further with next and previous buttons, plus an auto-play feature that stops playing once interaction starts.
About that auto-play thing — it’s a bonafide CSS trick:
- First I slowly offset the scroll snap points to the right, making the scroll area follow along due to being snapped to them.
- After having scrolled the width of a whole slide, I deactivate the snapping. The scroll area is now untied from the scroll snap points.
- Now I let the scroll snap points jump back to their initial positions without them “snap-dragging” the scroll area back with them
- Then I re-engage the snapping which now lets the scroll area snap to a different snap point 🤯
