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!

Here's that @CodePen link 🫶 Should be good in all browsers 🤙 No CSS scroll animation support? Falls back to Intersection observer ✨

Indeed I like the way you toggle the theme much more than the highlight.

This is some. crazy CSS love it

Really wish X to add possibility to have code snippet in the posts. Readability is a way too low in such posts

Are scroll-driven events available on the main browsers?

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! 👇

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 combine scroll-driven animations with background-clip to create gradient text reveals 😍 p { animation-name: move-bg, fade-in; animation-fill-mode: both; animation-timing-function: linear; animation-timeline: scroll(root); animation-range: 0 100vh, 40vh 100vh; } /* Multiple animations with shared timeline and different ranges 👀 */ keyframes move-bg { to { background-position: 50% 100%; } } keyframes fade-in { 0% { opacity: 0; } } The trick here is creating a large background with a radial gradient and using background-clip: text on the element with color: transparent ✨ p { background: radial-gradient(50% 100% at 50% 100%, hsl(var(--accent, 10) 90% 95%), hsl(var(--accent, 10) 90% 50%), transparent 50%); background-size: 400% 600%; -webkit-background-clip: text; background-position: 50% 0; } Then we animate the background-position to reveal the colorful part that reveal the text 😎 Another #AppleEvent related scrolling demo coming tomorrow 😅 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! 👇

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 create these trending expanding scroll indicators with scroll-driven animations and flex 🤙 .indicator { animation: grow; animation-range: contain calc(50% - var(--size)...; animation-timeline: var(--card); } @keyframes grow { 50% { flex: 3; }} What's the trick? Put the indicators in a container using flex layout and set a width larger than the number of indicators 😉 .indicators { aspect-ratio: 7 / 1; display: flex; } Importantly, set no gap 🤏 To mimic the gap set a transparent border on each indicator and set the background using padding-box .indicator { background: linear-gradient(#fff, #fff) padding-box; border-radius: 50px; border: 4px solid transparent; } Now for the animation. You want to create a view-timeline for each card that moves across 🤙 li:nth-of-type(1) { view-timeline: --one inline; } li:nth-of-type(2) { view-timeline: --two inline; } Make sure they use the inline axis too! The trick is hoisting these view-timeline so the indicators can use them with timeline-scope 👀 .track { timeline-scope: --one, --two, ...; } All that's left is for you to create the animation piece using some calc with the card size ⚡️ .indicator { --size: calc(var(--card-width) * 0.9); animation: grow both linear; animation-range: contain calc(50% - var(--size)) contain calc(50% + var(--size)); } .indicator:nth-of-type(1) { animation-timeline: --one; } .indicator:nth-of-type(2) { animation-timeline: --two; } @keyframes grow { 50% { flex: 3; }} And there you have it, responsive scroll indicators using CSS scroll-driven animations 😎 Sprinkle a little JavaScript to make them clickable and scroll the the right card ✨ const shift = (event) => { if (event.target.tagName === "BUTTON") { const index = [...event.target.parentNode.children].indexOf(event.target); const item = document.querySelector(`li:nth-of-type(${index + 1})`); item.scrollIntoView({ behavior: "smooth", inline: "center" }); } }; As always, any questions or suggestions, let me know.

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.

CSS Tip! 📜 You could create a sticky popout bento effect with position: sticky and scroll-driven animation 🤩 The trick is to use position: sticky with bottom instead of top like we would usually 🤙 Then we can use scroll-driven animation as a progressive enhancement to fade things and move the phone around ✨ section { view-timeline-name: --section; } .phone { scale: 1.5; translate: 30% 0; animation-name: slip, slide; 👈 2 scroll animations animation-timing-function: linear; animation-fill-mode: both; animation-range: 👈 2 ranges entry 50% entry 60%, exit 10% exit 25%; animation-timeline: --section; } keyframes slip { to { translate: -5% 0; scale: 1 } } keyframes slide { to { translate: -5% 30%; } } If scroll-driven animations aren't supported, we still provide a neat effect using position: sticky alone 😎 The trick to that is having an absolutely positioned card that comes up from beneath the phone image and gives the illusion that they're joined.

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! 👇

Amazing what we're going to be able to do with CSS alone! 🔥 CodePen.IO link below! 👇

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! 👇

CSS Trick! 🤙 You can create gradient borders on translucent elements using mask-clip and mask-composite with a pseudo-element 🔥 .gradient-border::after { mask-clip: padding-box, border-box; mask-composite: intersect; mask: linear-gradient(transparent, transparent), linear-gradient(white, white); } It's the same "Transparent border trick" from before. But, now you apply it to a pseudo-element 😎 The trick is to create a pseudo-element with a gradient background and then mask it so we only see the part we want, the border ✨ mask-clip defines the area affected by a mask. Similar to how you can define background-size. Using padding-box and border-box constrains the two masks. mask-composite is the magic part ✨ It defines a compositing operation for stacked mask layers. Using intersect means that the parts that overlap get replaced. And this seems to work in all browsers 🙌 As for the rest of the styles... – Make sure you set pointer-events: none on the pseudo-element – Make sure it fills the parent element. You can use position: absolute and inset: 0 – Make sure the background fills the space including the border-width. You can use calc to achieve that: --bg-size: calc(100% + (2px * var(--border))); background: var(--gradient) center center / var(--bg-size) var(--bg-size); That's it! 🚀 Gradient borders on translucent elements. You can set all the backdrop-filter: blur() you like! 😅 CodePen.IO link below! 👇

CSS Tip! ✨ You can lean into form control state and layered backgrounds to create input status strokes 😎 input:valid { --valid: 1; } input { background: var(--bg) padding-box, ..., var(--valid-bg) calc((1 - var(--valid)) * 100cqi) 0 / 100% 100% border-box; } The trick is to layer up backgrounds using background-clip to leave a border space 🤏 Applying a transparent border gives you the space for the layered background to transition in 🎞️ Then you can use custom properties to dictate the background-position of each layer. By default, the valid and invalid layers are positioned outside the bounding box. But when one of those states is active, the background layer transitions in to 0 0. To respect people's animations preferences, we can wrap that transition in a media query 🤙 @media (prefers-reduced-motion: no-preference) { input { transition: background-position: 0.5s; } } Was revisiting techniques around :has and :user-valid and it dawned that you could do it like this too! Hope you find it useful! p.s Don't rely on color to communicate form status. It's a cool trick though for an added touch ✨ 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 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 the lh (line-height) unit on background layers to emphasize multiple lines of text responsively without extra elements! ⚡️ h1 { background: linear-gradient(white, white), grey; background-size: 100% calc(var(--lines) * 1lh), 100% 100%; background-clip: text; color: transparent; } Here you emphasize the first two lines of the heading with white using a sized background-image layer It has a size of 2lh ✨ Then the rest of the element is colored with whatever other colors you want to use as layers. If you watch the video, you can see different colors used for different lines and then fade it out if you wish. You could do whatever you like with it 😎 Neat part is that it's responsive. The font-size is set with a clamp and you can resize the viewport or the element and the number of lines emphasized will remain 🤙 Last but not least, make sure to use background-clip: text and color: transparent so the background shines through 🔥 Also, note that if you're only looking to highlight the first line, you can still use the :first-line pseudo 🫶 Have a play with it and see what you can come up with!
