CSS-Only Carousel

Celý článek

It's kind of amazing how far HTML and CSS will take you when building a carousel/slideshow.

1. Setting some boxes in a horizontal row with flexbox is easy.
2. Showing only one box at a time with overflow and making it swipable with -webkit-overflow-scrolling is easy.
3. You can make the "slides" line up nicely with scroll-snap-type.
4. A couple of #jump-links is all you need to make navigation for it, which you can make all nice and smooth with scroll-behavior.

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:

1. First I slowly offset the scroll snap points to the right, making the scroll area follow along due to being snapped to them.
2. After having scrolled the width of a whole slide, I deactivate the snapping. The scroll area is now untied from the scroll snap points.
3. Now I let the scroll snap points jump back to their initial positions without them "snap-dragging" the scroll area back with them
4. Then I re-engage the snapping which now lets the scroll area snap to a different snap point 🤯

Cool.

JavaScript-powered slideshows (e.g. with Flickty) can be real nice, too. There is just something neat about getting it done with so little code.
