Hey @jh3yy , looking awesome, could you please drop a link to this page if you have it. TY

Please, we need a codepen for this 🥹

Let's say I have a procedural animation being rendered to a canvas element, rather than a video playing. Can I translate these concepts to work with that instead???

jhey ▲🐻🎈2 years ago

For real 💯 You can put anything behind it. It's an element with a black background and white color. The SVG filter jus' takes out all the white pixels 🤙

$Future CSS Tip! 🍏 You can create that Apple style blow out text effect with CSS scroll-driven animations ⚡️ No JavaScript! The trick is to animate SVG text along the z-axis using 3D transforms 👀 .word { animation: blow-out both ease-in; animation-timeline: --section; 👈 animation-range: exit-crossing 10% exit 0%; } keyframes blow-out { to { transform: translate3d(0.05ch, 0, 99vh); } } The animation makes the text cover the viewport and blends into the next section which has the same background-color 🤙 The section is set to 200vh. But the wrapper around the SVG text defines perspective and transform-style .section__content { transform-style: preserve-3d; 👈 perspective: 100vh; } We're using an SVG to maintain the crispness of the text as it scales up ✨ Use these attributes on the within the SVG to align things 🤙 Your Name It's the last day of #AppleEvent week but I do have some more of these I'll put together next week 😉 CodePen.IO link below! 👇$

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 👇

Future CSS Tip! 📜 You can create these landing page effects with CSS scroll-driven animations and zero JavaScript 🔥 Blurred text on exit? 👀 @keyframes fade { to { opacity: 0; filter: blur(2rem); } } h2 { animation: fade; animation-timeline: view(); animation-range: cover 40% cover 85%; } Lots of treats in this one! ✨ How about the circular shape on scroll? That's an animated clip-path 😮 @keyframes unclip { to { clip-path: ellipse(220% 200% at 50% 175%); } } Create a clip-path with a large size that's offset vertically. On scroll, animate it in ⭐️ .content { clip-path: ellipse(220% 200% at 50% 300%); animation: unclip both linear; animation-timeline: --article; animation-range: entry; } That second section combines unclipping with scaling down an image at the same time 🤓 Using the same animation-timeline 🫶 @keyframes scale-down { 0% { scale: 5; } } img { animation: scale-down; animation-timeline: --article; 👈 animation-range: entry; } Every section gets a scoped view-timeline of --article. That's scoped so we can reuse it for all the animations we need 🙌 article { view-timeline-name: --article; } Honestly, the more you play with this stuff, the more tricks you will find 💯 And it also makes you think "Wow!

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! Thought this smaller example would be easier to grok for people 🙏 It's also covered with JavaScript if you really want it for your sites 🤙 CodePen.IO link below 👇

Future CSS Tip! 🔮 You can create sweet scroll-driven micro-interactions using CSS scroll-driven animations 😎 .avatar { animation: scale-down; animation-timeline: scroll(); animation-range: var(--header-range); } @ keyframes scale-down { to { scale: 0.3; } } What's happening in this one? 👀 1. Avatar moves and scales down as the header sticks 2. Name changes color and slides over 3. Header darkens to give the text contrast 4. Header gets a shadow 5. Notice the avatar scrub too! 👀 It's scroll-driving the sprite animation technique we went over earlier in the week ✨ So much fun! ✨ Could even tie in the new easings from earlier too!

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. And then using the --header-height in the different animation-range ✨ Give it a try! ⭐️ CodePen.IO link below! 👇

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!

CSS Trick 🫠 You can create gooey effects with filter using CSS or SVG if you want color 🎨 .blobs { filter: blur(20px) contrast(30); } .blobs { filter: url(#goo); } The trick is to blur the thing, then cut the blur off with contrast. You can make some cool effects with it ✨ The CSS approach is basic and limits you to black and white. You need to blur the subject and then use contrast to lessen the blur. .blobs { filter: blur(20px) contrast(30); } The SVG approach gives you a lot more freedom. That looks like a lot 😬 What the filter does is take some source and pipe it through different effects. At a high level, you're doing this: 1. Blur the subject with standard deviation "stdDeviation" 2. Mess with the alpha channel values inside feColorMatrix to get the contrast 3. Composite the effects Good thing with SVG filters is you can rinse and repeat and use them on other things 🤙 Have a play with the demo and check out the DevTools where you can see the effects of using different values 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!

You can flip the scrollbar position for an element using a double invert 🙂 ul, li { scale: 1 -1; } /* y-axis flip */ A negative scale inverts the element on that axis ✨ For a bonus, control the invert on scroll using scroll-driven animations as the scroller enters the viewport li { scale: 1 -1; animation: flip both steps(1, end); animation-timeline: --list; animation-range: entry; } @keyframes flip { to { scale: 1 1; } } That's all there is to it 😎 Got a vertical scroller and want the scrollbar on the left? ul, li { scale: -1 1; } Got a horizontal scroller and want the scrollbar on the top? ul, li { scale: 1 -1; } The trick here is that you flip the scroller on the desired axis using a negative scale. And then you flip the children on the same axis with the same negative scale to put them back the right way ⭐️ CodePen.IO link below 👇

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 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. The mask one animates the mask size across three mask layers and uses a mask composite to exclude the pieces that don't need to be shown 🤙 As always, any questions or requests, hit me up! 🙏 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! 👇
