Similar technique 🤙 1. Take a scroll-snap list 2. Apply CSS scroll animations ✨ img { animation: flow; animation-timeline: --cover; } keyframes flow { 0% { transform: translate(-80%, 0) rotateY(-33deg); } } Few lines of CSS make it a progressively enhanced animated list 🔥

Here's the @CodePen link 🚀 Definitely required as I can't fit a decent chunk of keyframes into that post without making it an essay 😅

what is the flow animation and --cover ?

The keyframes were a little long to squeeze in here 🤏 "flow" is the animation-name "--cover" is the animation-timeline The animation-timeline is based on the list item position and the animation is applied to the image that's contained 🤙

@X should bring syntax highlighting just for this guy! 👀

I remember doing this in flash / actionScript 👀

Future CSS Tip! 🍏 You can create this Apple-style photo scroller by combining CSS scroll-driven animations and CSS scroll-snap 😍 Peep those changing captions 👀 No JS! img { animation: highlight both linear; animation-timeline: view(inline); 👈 Horizontal animation-range: cover 0% cover 50%; 👈 Finish } @ keyframes highlight { 50% { translate: 0 0; scale: var(--starting-scale); 👈 props opacity: var(--starting-opacity); 👈 } 100% { translate: 0 0; scale: 1; opacity: 1; } } Without the animation support, you get a standard unordered list containing some s 🤙 How do we swap the captions though? The "trick" is to use position: absolute on the figcaption and animate their opacity based on the ViewTimeline of their parent list item 😎 figcaption { animation: show both linear; animation-timeline: --list-item; } @ keyframes show { 0%, 45%, 55%, 100% { opacity: 0; } 50% { opacity: 1; } } li { view-timeline-name: --list-item; view-timeline-axis: inline; 👈 important! } The parent of the scroll track uses position: relative so all the captions sit in the middle even though they are in the right place for the markup 🙌 The last bit is the scroll-snap 🤙 Not much to it at all. Wrap the list and make it scrollable. Then add scroll-snap-type .wrapper { scroll-snap-type: x mandatory; overflow-x: scroll; } Then make sure each list item has scroll-snap-align set on it li { scroll-snap-align: center; } That's it! Pretty cool demo to put together and see how to do this stuff with these APIs 🤓 A lot of cool little tricks to pick up for writing your CSS! ⭐️ CodePen.IO link below! 👇

CSS Tip! 📜 You can use scroll-driven animations to progressively enhance collapsing a floating call to action 🤏 .cta { animation: shrink; animation-timeline: scroll(); animation-range: 0 100px; } @​keyframes shrink { to { width: 48px; } } That's the gist of it. Use the body scroll position with animation-timeline: scroll(). Define the animation-range as when you have scrolled 100px. There's a little more though 🤓 That would "scrub" the width animation. Ideally, you want to trigger that animation. You could animate a custom property with steps() timing and use that to define the width ✨ @​property --scrub { syntax: ' '; inherits: true; initial-value: 0; } body { animation: scrub both steps(1, end); animation-timeline: scroll(); animation-range: 0 100px; } Then transition the --scrub property on the CTA and use it for the width 🤙 .cta { transition: --scrub 0.2s; width: calc(48px + (120px * (1 - (var(--scrub) / 100)))); } Other animations are a matter of preference and timing. For example, you could then make the hand wave, scale down the size, and then slide a gradient across 😉 They have the same structure and technique as the original concept. Waving the hand? 👋 Run it twice, offset the transform-origin. .hand { animation: wave both linear 2; animation-timeline: scroll(); animation-range: 30vh 50vh; transform-origin: 65% 75%; } @​keyframes wave { 50% { rotate: 20deg; } } How's it progressively enhanced? Wrap everything in a @​supports query and a @​media query. If there isn't support, users still get a good experience. It's a floating action button that's circular and already collapsed 🤙 @​supports(animation-timeline: scroll()) { @​media(prefers-reduced-motion: no-preference) {...} } Definitely have a play with the code. Amazing what we're going to be able to do with CSS alone! 🔥 CodePen.IO link below! 👇
