CSS in 2024 🤯 You can create a range slider with updating value tooltip and color changing track without using any JavaScript 🤯 ::-webkit-slider-thumb{ view-timeline: --thumb inline; } Scroll animation on the slider thumb that animates a number between the "min" and "max" of the range 😅 @​property --value { 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 the tooltip can use the value too! :root { timeline-scope: --thumb; } Then use it in the counter which goes in the tooltip 😇 .tooltip { counter-reset: val var(--value); } .tooltip::after { content: counter(val); } Then the accent color is based on the value too 🎨 [type=range] { accent-color: hsl(var(--value) 90% 65%); } The magic from the quoted post is using anchor positioning on the range thumb to position that tooltip 👏 Never thought of that when working on the spec for this API. This API lets you tether elements to other elements. Using the pseudo is a clever move! ::-webkit-slider-thumb { anchor-name: --thumb; } .tooltip { position: absolute; anchor-default: --thumb; left: anchor(50%); bottom: calc(anchor(top) + 25%); } The last piece is the little bounce transition... 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. Lots of little tricks to break down with it for sure! 💯 As always, any questions, let me know! Also, this one only works in Chrome Canary with the Experimental Web Platform Features flag enabled ✅ This one almost feels like rocket science ha 🚀 CodePen.IO link below! 👇

CSS variables are live and they are POWERFUL. Now Live on Product Hunt 🚀 ➡️ Create a design system "So you can stay consistent and build much quicker." Define global styles like colors, gradients, sizes, and box shadows. ➡️ Use your variables everywhere "So you never have to manually enter a border color again." You're not limited to just sizes, colors, and font families. Use variables in gradients, box shadows, transforms, and more! ➡️ Start with libraries like Open Props, expertly crafted CSS variables "So you can use a tried and true system, and so we can standardize our Projects." Because there are no abstractions, you can use existing CSS variable libraries like Open Props, an expertly crafted library of CSS variables, and the recommended starting point in Webstudio. ➡️ Create complex micro-interactions "So when you hover a link, you can change any children's styles." CSS variables go beyond reusability! You can define variables anywhere in the navigator, such as on a link, and modify the variables on hover. Then, you can use those variables on the children to create complex micro-interactions! ➡️ Design and build simultaneously "So when deciding that perfect border color, you can arrow through all your options." Experimenting on the canvas just got a whole lot better. Now, you can arrow through your variables and see them rendered on the canvas to see which works best. ➡️ Change variable by breakpoint "So you can make the variables look great, no matter the screen size." CSS variables in Webstudio use the same UI as the rest of your styles, enabling breakpoints to work the same way. ✨ Building with design systems gives a HUGE boost in speed, consistency, and maintainability.

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 👇

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! 👇

Elon Musk says working will be "optional" soon. Robots and AI will eliminate non-physical jobs, creating a "Universal High-Income" where everyone gets what they want. But a Yale paper shows the economics behind his prediction are far more brutal than he suggests. I'm talking about the paper titled "We Won't Be Missed." It concludes: "Half the workforce could stop working tomorrow and GDP wouldn't budge." i.e. humans become economically meaningless. The paper splits all work into two categories: 1) Bottleneck work This work is essential for growth. Energy production, logistics, scientific discovery, and infrastructure. The economy cannot grow unless this work scales. 2) Accessory work It's non-essential. Arts, hospitality, therapy, and fine dining. It's nice to have, but not required for growth. AGI systematically takes over everything that's mission-critical. Some accessory work stays human, not because AGI can't do it, but because we have surplus workers and it's not worth the compute. In other words, your future salary will be based on the computational cost of replicating your work. As compute gets exponentially cheaper, your wage ceiling plummets. The economy grows, productivity increases, but your value is tied to declining tech costs. Yale's paper concluded: Labor's share of GDP converges to zero. All income flows to owners of computational resources. The transition speed determines how painful this gets. If technology develops faster than computing scales, we get jagged disruption, with some workers receiving huge premiums before crashing. If compute scales faster, we get gradual, predictable decline in wages. In my opinion, there is a paradox that Musk missed here. Work being "optional" is an illusion. Humans need work, maybe not for survival, but for purpose. The existential question is: Would people still choose to work when it's economically meaningless... and when your contribution doesn't matter for progress or prosperity?

007/100 Buttons. This button was way more complex than I first thought. I love the page transition on the Truus site that Dennis Snellenberg and Jordan Gilroy worked on. So I wanted to use that drawing SVG Path idea somehow and fit it into a button. In best case with a mask effect. The idea was to have an SVG path in the background that fills the button. At the same time, this path should also be used as a mask to reveal the differently colored text. The SVG should also be replaceable and work with other SVGs. For the path animation, I can use the DrawSVGPlugin from GSAP. Sounds like a solid plan. I built the button so far, and it worked great in Chrome and Firefox. In Safari, nope. I used an SVG mask that I referenced through CSS. But Safari can’t handle that properly when the path inside the mask is animated, so the animation lags. There was no simple solution for that. At least I didn’t find something. So I had to rebuild the button in another way. What I found was that the SVG mask animation works in Safari when the mask is placed on the desired element inside the SVG. That’s where foreignObject comes in, it allows you to use normal HTML elements inside an SVG. Using that, I rebuilt the hover text inside the SVG. I then referenced the mask on the foreignObject with a bit of JavaScript. And it worked! The button’s structure looks more complicated than I wanted it to be, but that happens quite often when you need to make something work across different browsers 😃 Crafting 100 Buttons with Osmo ⏳ Total time: 96h

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! 👇
