3D CSS image slider works well on device 🤙 li { --item-width: clamp(120px, 20vmin, 12rem); --radius: calc( (var(--item-width) / sin(var(--inner-angle))) * -1 ); } It's cool how you can use a clamped value with "calc"

Insane! 🤩 But it’s only for Chrome, right?

Yep – But I updated the demo so it falls back to using GSAP ScrollTrigger if the browser doesn't support CSS scroll animations 🤙

That is so incredible! Might use that for my page 🔥 Thanks for sharing!
![CSS Tip! 🤯 You can create a CSS-only version of this balance slider using a scroll animation on the underlying input[type=range] 🚀 ::-webkit-slider-thumb { view-timeline: --thumb inline; } Scroll animation driven by the slider thumb animates a number between the "min" and "max" of the range 😅 @property --value { inherits: true; initial-value: 0; syntax: ' '; } @keyframes sync { to { --value: 100; }} Tie that up to the contain animation-range ⚡️ .control { animation: sync both linear reverse; animation-timeline: --thumb; animation-range: contain; } Hoist the view timeline so all the parts of the control can use it! .control { timeline-scope: --thumb; } Use that value in a counter which is used for the labels. Create a low and a high for each side 😇 .control__label { counter-reset: low var(--value) high calc(100 - var(--value)); } .control__label::before { content: "COFFEE " counter(low) "%"; } .control__label::after { content: counter(high) "% MILK"; } That's the magic of updating the label values ✨ For the big track, it's a fake track. You can make use of the same --value property and do some calc() to work out the width of each part. .control__track::before { width: calc(var(--value) * 1% - 0.5rem); background: var(--coffee); border-radius: 4px; transition: width 0.1s; } The width leaves a little gap for the indicator piece 🤙 The color calculation for --coffee isn't too wild but again you can use the same --value .control__track { --coffee: hsl(24 74% calc( 24% + (30% * ((100 - var(--value, 0)) / 100)) / 1 ) / 0.4); } Now for the last piece. Making the track change height. You could set up another custom property and animate its value using the --thumb timeline too 🔥 @property --shift { initial-value: 0; inherits: true; syntax: ' '; } @keyframes shift { 0%, 31%, 61%, 100% { --shift: 0; } 32%, 60% { --shift: 1; } } Then use that --shift to update the translation of the label and height of the track 🤓 .label { transform: translateY(calc(var(--shift) * 50%)); transition: transform var(--speed) var(--timing); } Cool part here is that you can use the control to work out the @keyframes percentages 😅 Oh. And the timing for that little bounce? Use the linear() function 😎 :root { --timing: linear( 0, 0.5007 7.21%, 0.7803 12.29%, 0.8883 14.93%, 0.9724 17.63%, 1.0343 20.44%, 1.0754 23.44%, 1.0898 25.22%, 1.0984 27.11%, 1.1014 29.15%, 1.0989 31.4%, 1.0854 35.23%, 1.0196 48.86%, 1.0043 54.06%, 0.9956 59.6%, 0.9925 68.11%, 1 ); } Should probably do a video on this one. Lots of little custom property tricks for sure! 💯 It's not too far off the range slider with the tooltip that came up previously As always, any questions, let me know! Also, this one only works in Chrome currently ✅🥲 This one's a bit rocket science ha 🚀 CodePen.IO link below! 👇](https://image.24vids.com/tw-1748809599598399792/ext_tw_video_thumb/1748804672406843392/pu/img/xbvSosI5c_q3Oq2B.jpg)
![CSS Trick 🧲 You can create magnetic links with the power of custom properties and some JavaScript 💪 a { translate: calc(clamp(-1, var(--x), 1) * var(--pad-x)) ...; transition: translate var(--s, 1s) var(--ease, var(--elastic)); } a:hover { --s: 0s; } The trick here is to pad out the list items wrapping your links and use that as a translation limit 🛑 Start by using some JavaScript to calculate a value between -1 and 1 for both the x/y axis on pointermove for each list item, not the link! 🔗 If your pointer was at the center of the item, you'd get [0,0]. If it was in the top right, you'd get [1,-1] ☝️ It's worth checking out the JavaScript snippet to see how the mapping function works. Essentially, you create a function that when given a value between two bounds, will give you a mapped value back 🤙 const mapX = mapRange( item.offsetWidth * -0.5, item.offsetWidth * 0.5, 1, -1 ) Then, on pointermove, you plug the pointer position in to get the value back out and pass that into your CSS const x = mapX(item.centerX - event.x) document.documentElement.style.setProperty(--x, x) When the pointer leaves the list item, you make sure to reset these values back to 0 ✨ Once CSS has your values, it's the trick of updating the translation of each part You know that in each axis, you only want to translate the link by the padding amount li a { translate: calc(clamp(-1, var(--x), 1) * var(--pad-x)) calc(clamp(-1, var(--y), 1) * var(--pad-y)); transition: translate var(--speed, 1s) var(--ease, var(--elastic)); } This will translate the link within the list item by the desired amount. The cool part here is that you can set an offset for the text inside the link and have that move at a different rate ⭐️ By only updating the --pad-x/y custom properties for the inside the link, you can control how much it moves nav a span { --pad-x: 0.25rem; --pad-y: 0.25rem; } And the last piece, how do you update the behavior for transition speeds? And so it springs back like that? Again, use custom properties ✨ a:hover { --s: 0s; } a { transition: translate var(--s, 1s) var(--ease, var(--elastic)); } By default, a link will use --elastic easing via linear() and have a transition-duration of 1s. When a link is hovered that speed becomes 0s because you want the link to magnetise to your pointer. How about that little gap between when your pointer enters the item but hasn't hovered the link? Set a different transition so it transitions to being hovered 🫶 nav li:hover a { --ease: ease-out; --speed: 0.1s; } That's kinda it! 🙌 Use JavaScript (~40 loc) to get the information and then let CSS do all the lifting for you 💪 Any questions or suggestions, let me know 🙏 If you want a walkthrough video, also let me know please 🙏 CodePen.IO link below 👇](https://image.24vids.com/tw-1745716136824672271/ext_tw_video_thumb/1745612660081881088/pu/img/SsGz-uqmfdr1KZ7H.jpg)
![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. I've put a JavaScript fallback in to use GSAP in browsers that don't have scroll-driven animations 🫶 CodePen.IO link below! 👇](https://image.24vids.com/tw-1743737760773705824/ext_tw_video_thumb/1743734045748641792/pu/img/nFQ1z9S-iN4AY8SN.jpg)
![CSS Tip! 💪 You can create these tab controls with CSS :has() + radio buttons ✨ .tabs:has(input:nth-of-type(3)) { --count: 3; } .tabs:has(:checked:nth-of-type(3)) { --active: 2; } .tabs::after { translate: calc(var(--active, 0) * 100%) 0; width: calc(100% / var(--count)); } Two CSS :has() tricks here combined with a rendering trick 🤙 The tab control is a container using display: grid. You can use :has() to count the number of tabs in the container: .tabs:has(input:nth-of-type(3)) { --count: 3; } .tabs:has(input:nth-of-type(4)) { --count: 4; } Using the cascade, the last valid :has() gives you the number of tabs 🫶 Once you know the number of tabs, you know how to size the indicator: .tabs::after { content: ""; position: absolute; height: 100%; width: calc(100% / var(--count)); } It's a pseudoelement that uses --count to determine its size 📏 The next :has() trick is determining which tab is active or :checked as it's an input [type=radio] .tabs:has(:checked:nth-of-type(2)) { --active: 1; } .tabs:has(:checked:nth-of-type(3)) { --active: 2; } You can use a zero-indexed translation here. If the second input is :checked, set --active: 1, then translate the pseudoelement on the tabs to that position 👉 .tabs::after { translate: calc(var(--active, 0) * 100%) 0; } The last rendering trick is using mix-blend-mode 👀 The tabs have a black background-color, the pseudoelement is white, and the label text is white. When you use mix-blend-mode: difference on the pseudoelement it will give this effect that the text transitions from white to black sliding across 😎 .tabs::after { color: hsl(0 0% 100%); mix-blend-mode: difference; } You can totally mix up the colors here though and go with a different effect. The mechanics of how you can use CSS :has() is the main point here 🙏 As always, any questions, suggestions, etc. let me know CodePen.IO link below! 👇 (There's even a Tailwind CSS play for this one too 👀)](https://image.24vids.com/tw-1746099478656901617/ext_tw_video_thumb/1746099293872898048/pu/img/oonp9Ek6MULFcFjk.jpg)
![CSS Tip! 🤙 You can use mask-composite and some JavaScript to create this pointer proximity following glow border ✨ .glow { mask-composite: intersect; mask-clip: padding-box, border-box; mask: linear-gradient(#0000, #0000), conic-gradient(#0000 0deg, #fff, #0000 45deg); } The trick is to mask a background-image with a combination of mask layers. mask-composite: intersect; means the mask used will be the intersection of the layers 🔥 use source-in, xor; in browsers that don't support intersect; In this demo, you can use pseudoelements and rely on scoped custom properties to do a lot of the heavy lifting for you 🙌 Once you've masked the background, you need to update the starting angle of the conic-gradient on pointermove 👆 You can work that out by getting the center point of each card and then calculating the angle between that and the pointer with Math.atan2 🤓 let ANGLE = Math.atan2( event?.y - CARD_CENTER[1], event?.x - CARD_CENTER[0] ) * 180 / Math.PI ANGLE = ANGLE < 0 ? ANGLE + 360 : ANGLE; CARD.style.setProperty('--start', ANGLE + 90) You plug that into your conic-gradient mask as a custom property accounting for --spread ⚡️ conic-gradient(from calc((var(--angle) - (var(--spread) * 0.5)) * 1deg), #000 0deg, #fff, #0000 calc(var(--spread) * 1deg)); To get the blur, you apply a blur to the glow container on each card 🤙 .glows { filter: blur(calc(var(--blur) * 1px); } That's it! Layers of masks that are clipped and composited before being blurred 😎 The added trick is to fade each one in when the pointer is in the defined proximity of the card. For example, don't show unless within 100px of a card. You can see that in the video. Check out the JavaScript code for that 🫶 Couldn't resist making this one 😁 CodePen.IO link below! 👇](https://image.24vids.com/tw-1734369933558010226/ext_tw_video_thumb/1734365662590418944/pu/img/320Dgq_k3RZoZOFV.jpg)
