CSS Tip! ✨ You can create these parallax effects and image cross-fades with scroll-driven animations 🤙 img { animation: fade; animation-timeline: view(); mix-blend-mode: plus-lighter } img:last-of-type { animation-direction: reverse; } @keyframes fade { to { opacity: 0; }} This one's fun! 😁 The trick with the cross-fading image is... to make use of one animation that runs at the same time on two images inside a container. You use the same animation, animation-timeline, and animation-range. But, you use animation-direction: reverse on one of the images so they go in the opposite direction 🫶 The use of mix-blend-mode: plus-lighter; produces a better cross-fade result 💯 A viewTimeline (view()) works because you know that both images are the same height. The range you can use is img { animation-timeline: view(); animation-range: cover 45% cover 55%; } That means when the image has covered 45% of the scrollport (In this case, the window), start the animation. And finish when it has covered 55% 🎬 How about the slight parallax? This is a trick with calc(). You know the top of the small image and the big image line up. And you can do this by absolutely placing the caption outside of the small image. The trick is to translate the small image by a distance so it lines up with the bottom of the big image. You can do that like this :root { --catch-up: calc( var(--big-height) - var(--small-height) ); } @keyframes move { to { translate: 0 var(--catch-up); }} Then drive that animation with a scroll-driven animation using the container of both images as the driver 🤙 /* section contains both images / section { view-timeline: --container; } .img-fader { animation: catch-up both linear; animation-timeline: --container; animation-range: 50vh calc(100vh + (var(--big-height) 0.25)); } That's it! Scroll-driven image cross-fading and parallax effects without any JavaScript. This demo will work in all browsers as there is some JavaScript in place where the API isn't supported 🤙 To do that, it uses GSAP ScrollTrigger 🏆 As always, any questions, requests, etc. hit me up! 🤙 CodePen.IO link below 👇show more

Here's that @CodePen link! 🚀 You can jam on this demo today in all browsers. There is some JavaScript in place if the scroll-driven animations API isn't supported 🤙 GSAP to the rescue! 🏆

For a little history and insight behind cross-fading with plus-lighter for folks, here is @jaffathecake's excellent article behind it:

Good share Martin! 🙏 Almost embedded in my mind from when I started working with View Transitions 😅 The number of times I pinged Jake and it was my own problem with a mix-blend-mode thing 🤦‍♂️ This is the spot from the View Transition docs for people interested 🤙 Jake's blog is also a gold mine of interesting deep dives, etc. 👉

Wow, how it would be in responsive mode?

jhey ▲🐻🎈2 years ago

Ha – Great minds... 🤙

So good. Thanks for tutorial.

niftesty 🫐2 years ago

Browser compatibility?

jhey ▲🐻🎈2 years ago

Specifically the API is Chrome only atm. But, the demo will work everywhere as I've filled the functionality with GSAP and wrapped the API stuff in a supports query so it can be ripped out easy 🤙

Lo malo es que no está soportado en todos los navegadores

jhey ▲🐻🎈2 years ago

The API isn't, but the demo is 🤙 Will work in all browsers

CSS Trick 🍏 You can create that Apple-style blowout text effect with CSS scroll animations and fixed positioning ⚡️ .word { animation: blowout; animation-timeline: --section; } @keyframes blowout { 0%, 95% { background: transparent; } to { transform: translateZ(99vh); background: #000; } } The trick here is to fix the position of some things in your layout and then animate them based on their non-fixed containers ⭐️ The .word is position: fixed within a that has a height of 200vh section { view-timeline: --section; } section:first-of-type { height: 200vh; } Every section has a view-timeline: --section that creates a scoped ViewTimeline for each section's children 🤙 As that first section scrolls out of view, you increase its opacity and move it on the z-axis towards you. That gives it the impression of scaling up 🆙 .word { animation: blowout, fade-in; animation-timing-function: ease-in; animation-fill-mode: both; animation-timeline: --section; animation-range: exit-crossing 10% exit 0%; } You can use the exit-crossing range combined with the exit range to get a timing you like ✨ Definitely experiment with these ranges to see how they play. The timing function creates interesting effects too! At the same time as the text scales up, you need to fade in the video and the text that goes with it. Again, you can use the parent container's ViewTimeline --section p, video { animation: fade-in, fade-out; animation-timing-function: ease-in; animation-fill-mode: both; animation-timeline: --section; } p { animation-range: entry 10% entry 35%, exit 0% exit 25%; } video { animation-range: entry 0% entry 25%, exit 10% exit 35%; } The timings are slightly different here. Again, you can play with them to get something that feels right for you! @keyframes fade-in { to { opacity: 1; }} @keyframes fade-out { to { opacity: 0; }} Theoretically, you should be able to do something with animation-direction: reverse/alternate like yesterday's demo video { animation: fade 2 both linear alternate-reverse; } The trick with this effect is all about timing and creating containers that are bigger than the content and using them to drive the animations 🏎️ The scroll-driven signature is a bonus! ✍️ Perhaps a follow-up on that one 🤙 As always, any questions, requests, etc. Hit me up! With this demo, the GreenSock ScrollTrigger code is included where the CSS scroll-driven animations API is not supported 🙌 That means you could use this demo today! CodePen.IO link below! 👇

CSS Tip! 📜 You can create scroll-driven micro-interactions with animation-timeline and custom properties 🔥 .search { animation: shrink; animation-timeline: scroll(); animation-range: 0 calc(var(--header-height) * 0.5); } @keyframes shrink { to { width: calc(100% - var(--button-size); } } The --header-height is being used to dictate the container height for the header. You can use that for the animation-range used across different scroll animations 🤙 For another example, you can animate the box-shadow reveal on the header once the search has stuck 🍡 header { animation: shadow; animation-timeline: scroll(); animation-range: var(--header-height) calc(var(--header-height) * 1.5); } @keyframes shadow { to { box-shadow: 0 5px 10px hsl(0 0% 0%); } } Then you have the little extras! 🧸🎈 Everything powered by the scroll() animation-timeline which hooks into the page scroll.

CSS Tip! 🐳 You can add little details like this scale down on scroll effect with scroll-driven animations and some sticky positioning 🤙 section { animation: scale-down; animation-timeline: view(); animation-range: exit; } @keyframes scale-down { to { scale 0.8; } ] In this smaller example, you can lean into using the position to drive an animation that scales itself down as it leaves the viewport (Seen on the Apple Vision Pro site 🍏) The nice thing here is that if you don't have scroll-driven animations, the user still gets a good experience ✨ So how do you do it? There isn't much to it header { transform-origin: 50% 0%; animation: scale-down both ease-in; animation-timeline: view(); animation-range: exit; view-timeline: --header; } @keyframes scale-down { to { scale: 0.8 0.8; } } That's it. The layout makes use of position: sticky so that the element stays in the shot whilst you scroll the page. As it leaves the page, it scales down inside the 🫶 The other smol animation here is fading the overlay on the video out 😎 Real easy. You may notice the view-timeline you defined above for the 👀 header { view-timeline: --header; } You have a pseudoelement on the text content of the header that lives inside a header > section::before { background: hsl(0 0% 0% / 0.75); opacity: 1; animation: fade both linear; animation-timeline: --header; animation-range: exit-crossing 0% exit 0%; } @keyframes fade { to { opacity: 0; } } You use a slightly smaller range on this with exit-crossing to fade it out before you start the scale down animation 🤏 That's it!

CSS Tip! 📜 You can create scroll indicators with scroll-driven animations 📍 Reveal a shadow, mask the content, etc. .indicator--top { animation: reveal; animation-timeline: scroll(nearest); animation-range: 0 2rem; } @keyframes reveal { 0% { scale: 1 0; }} The trick here is to hook into the scroll position of the nearest scroll container with .indicator { animation-timeline: scroll(nearest); } Your reveal animation is going to scale the indicator up from 0 on the y-axis @keyframes reveal { 0% { scale: 1 0; }} The timeline is however much you want to scroll by before revealing the indicator. In this example, you're saying to reveal the indicator once the scroller has been scrolled by 2rem .indicator--top { animation-range: 0 2rem; } How do you make this work for the opposite indicator? Use animation direction and a range based on the end of the scroller .indicator--bottom { animation-range: calc(100% - var(--scroll-buffer)) 100%; animation-direction: reverse; } You can use this same concept for the different styles to reveal different indicators. The only one that's different is the mask.

CSS Trick 📜 You can trigger text highlights on scroll with scroll-driven animations 😎 mark { animation: highlight; animation-timeline: view(); } @keyframes highlight { to { --lit: 1; }} mark span { background-position: calc(var(--lit) * -110%) 0; transition: background 1s; } The trick is using a scroll-driven animation to flip a custom property on a element 🎚️ You flip the value between 0 and 1, and that transitions the background position of the element mark { --lit: 0; animation: highlight steps(1) both; animation-timeline: view(); animation-range: entry 100% cover 10%; } The background has to be applied on a child of the mark to see the change in the custom property 👀 mark span { background: linear-gradient( 120deg, yellow 50%, transparent 50%) 110% 0 / 220% 100% no-repeat; background-position: calc(var(--lit) * 110%) 0; transition: background-position 1s; } The trick is to set the background-size so that it's bigger than the element and then split the background-color in the middle using a linear-gradient 🤙 And the property flips fills in the color 🫶 That's it!

CSS Trick 📜 You can trigger text highlights on scroll with scroll-driven animations 😎 mark { animation: highlight; animation-timeline: view(); } @keyframes highlight { to { --lit: 1; }} mark span { background-position: calc(var(--lit) * -110%) 0; transition: background 1s; } The trick is using a scroll-driven animation to flip a custom property on a element 🎚️ You flip the value between 0 and 1, and that transitions the background position of the element mark { --lit: 0; animation: highlight steps(1) both; animation-timeline: view(); animation-range: entry 100% cover 10%; } The background has to be applied on a child of the mark to see the change in the custom property 👀 mark span { background: linear-gradient( 120deg, yellow 50%, transparent 50%) 110% 0 / 220% 100% no-repeat; background-position: calc(var(--lit) * 110%) 0; transition: background-position 1s; } The trick is to set the background-size so that it's bigger than the element and then split the background-color in the middle using a linear-gradient 🤙 And the property flips fills in the color 🫶 That's it! If there isn't support for scroll-driven animations, use JavaScript's IntersectionObserver API. The code for this is in the demo 😎 Cool example of using CSS as an IntersectionObserver!

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! 👇

CSS Trick! ⚡️ You can use scroll-driven animation with background-attachment to create a dynamic glowing card scroller without JS 🔥 section { animation:vibe; animation-timeline:--list; } @keyframes vibe { to{--hue:320;}} .glow {background: hsl(var(--hue) 80% 50%);} Here's how! 🤙 You can use the background-attachment trick used in other glow card demos 😎 article { background-attachment: fixed; } The difference here is that you aren't going to update the fixed background position with your pointer this time. It can remain fixed. The magic part is that as you scroll, the background will leave the card that's leaving and enter the card that's entering ✨ For the extra background glow, you can use a fixed pseudo element on the list container itself 💪 Once that's in place, you're only task is to change the color of the background as you scroll 🤔 Create a custom property declaration for the --hue @property --base { inherits: true; syntax: ' '; initial-value: 0; } Then create an animation that updates this value @keyframes accent { to { --hue: 320; }} The last piece is hooking it up to scroll and there is a little trick in here 👀 First, you need an inline scroll-timeline on the list ul { scroll-timeline: --list inline; } Then you can use timeline-scope to hoist that scroll-timeline up so a parent can use it. You then animate the custom property on this element and let the value cascade down to the places that need it 🔥 section { timeline-scope: --list; animation: accent both linear; animation-timeline: --list; } For example, the glow uses the --hue this way [data-glow] { background-image: radial-gradient( 150px 150px at 50% 50%, hsl(var(--hue) 100% 70% / 0.25), transparent ); } Lastly, scroll-snap is optional of course but plays nice with the scroll-driven animation demos ✨ The key for that is ul { scroll-snap-type: x mandatory; } li { scroll-snap-align: center; } That's it! Pretty fun trick to play with! 🤓 Any questions, let me know! Should we add it to the video walkthrough list? CodePen.IO link below! 👇

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 Trick 🤙 You can use scroll-driven animations on the inline axis to create list animations like in these cards 🫶 article { animation: vibe; animation-timeline: view(inline); animation-range: cover 40% cover 60%; } @keyframes vibe { 50% { scale: 1; filter: grayscale(0); }} Here you use a view() timeline with the inline axis set inside the function. This means you can hook into the horizontal scroll position of an element inside its scroller 🙌 In this demo, you set a default smaller scale and make each card grayscale 🤏 article { scale: 0.8; filter: grayscale(1); } Then the animation happens as each card enters from the right at 0% and leaves to the left at 100% 🎞️ 50% is the halfway point and in your keyframes you make each card grow and saturate at that point before returning to its original state ✨ scroll-snap provides a nice look-and-feel here and on mobile 🫰 It's really as straightforward as that but made so much easier with a few lines of CSS 💙 For the parallax effect, you can animate a background-position on the card or the object-position on an img depending on what you go with 🤙 Lastly, you can use this today with progressive enhancement by wrapping your scroll-driven animation code in @supports and @media ⚡️ Users without support still get a decent experience!

Future CSS Tip! 🔮 You can create responsive animated text reveals with CSS scroll-driven animations 🔥 section { /* The red element in the video */ view-timeline-name: --section; } p { animation: fill both linear; animation-timeline: --section; animation-range: cover; } keyframes fill { to { --fill: 1; } } No JavaScript required with this trick 😎 What's happening there then? Well, we're animating a custom property value using @ property. @ property --fill { initial-value: 0; syntax: ' '; inherits: true; } Then the trick is background clipping the text and filling it with a multiline background by animating the background-position to fill the text 🤓 span { background-position-x: calc(-100vmax + (var(--progress) * 100vmax)); background-clip: text; color: transparent; } CodePen.IO link below 👇

CSS Tip! ✨ You can create icon sprite animations using the steps() animation-timing function 🤙 You could use this to create little icon button animations, etc. 😎 But how do you do it? Like this 👇 button img { object-fit: cover; object-position: 0 0; } The image is a sprite strip of the frames in the animation. To animate the frames, you do something like this: [aria-pressed=true] img { animation: play 0.5s steps(20) forwards; } @ keyframes play { to { object-position: 100% 0; } } We are toggling aria-pressed in our scripts to show a pressed state and we can then fire the animation to play our sprite 🎉 Check out the video that breaks things down a little bit CodePen.IO link blow! 👇

CSS Tip! 🍬 You can create a CSS-only sticky CTA using position: sticky or scroll-driven animations 🤙 .cta { position: sticky; margin-top: 110vh; bottom: 2rem; /* 👈 Stick! */ } This is one way 👀 This first way relies on you setting a layout on the body and putting the CTA in a zero-space part of the layout body { display: grid; grid-template-columns: auto 0; } The children of the body are an element with your content and then the CTA. You could also use display:flex too. .content { flex: 1 0 100%; } .cta { place-self: end; } As you scroll the body, the CTA comes into view and sticks in position 🙌 That's one way. If you want to take it further and do something like flip between showing or not, maybe scale it up, or add some special easing, etc. an animation is another way 📜 First, change the styles for your CTA. Note the translate property that's powered by a custom property .cta { position: fixed; bottom: 2rem; right: 2rem; translate: 0 calc(20vh - (var(--show) * 20vh)); transition: translate 0.875s var(--elastic); } Next you need a custom property that you're going to animate @property --show { inherits: true; initial-value: 0; syntax: ' '; } Lastly, you animate this value on the body. As the property value changes, the value will trickle down to the CTA @supports (animation-timeline: scroll()) { body { animation: show-cta both steps(1); animation-timeline: scroll(root); animation-range: 0 10vh; } @keyframes show-cta { to { --show: 1; } } } Using @supports you can use this as a progressive enhancement. If scroll-driven animations are supported, use them. Otherwise fallback to using position: sticky 🤙 That's it! As always, any questions or requests, hit me up! 🙏 CodePen.IO link below! 👇

OK. I used a line or two of JavaScript for that 🙏😬 const updateDelta = ({ movementX }) => { document.documentElement.style.setProperty('--delta-x', movementX) } document.body.addEventListener('pointermove', updateDelta) But only so you can pass the movement delta to CSS and then reset the position with linear() to get that bouncy transition 😎 .hint { rotate: calc(clamp(-60, var(--delta-x) * -1, 60) * 1deg); transition: rotate 1s linear( 0, 0.2178 2.1%, 1.1144 8.49%, ... ); } Should probably do a video on this one.

Future CSS Tip! 📜 You can use scroll-driven animations like JavaScript's IntersectionObserver to animate highlights ✏️ mark { animation-name: highlight; animation-timeline: view(); } @keyframes highlight { to { --light: 1; }} mark span { background-position: calc((1 - var(--light)) * 110%) 0; transition: background 1s; } The "trick" is to animate a custom property with a scroll-driven animation. These will flip in a binary fashion if not using @property. And that's what you want. You can then use that value to set the style on the highlights ( ). What you see is the transition of a background-position to get the multi-line highlight. A technique posted on this account before 🤙 Added bonuses: – Could use another element for the author initials of a highlight and animate that in too. Here the pseudoelement is being used. But another accessible span would do the trick. – Highlight color is scoped inline via hue. – View transition theme switch for a bonus that looks like a triangle. Been messing with Vercel docs so was the easiest thing to go with 😅 CodePen.IO link below! 👇
