with a tiny bit of JavaScript enhancement take that CSS driven slider and give it "that little bounce™" - use pointer-events to calculate an overdrag - map that overdrag to a CSS custom property --stretch - apply style - profit 💀

Use masks for your scrollable areas Use the CSS at-rule `property` to register stops as animatable values. The browser treats your custom property as a `percentage`, so the mask edges transition smoothly. Result: scroll lists that fade at the edges, revealing content underneath. No JavaScript needed.

i wasn't aware of `animation-timeline` css property if I be honest. with it you can use css `scroll()` function to tie an animation with the scroll progress of a scrollable element. here im animating a `mask-image`s size based on the scroll progress with `2rem` of threshold.

3d hover effect made only using css. no javascript or framer motion used here. im utilizing css `preserve-3d` transform-style. the parent tilts 55deg (X-axis) and spins -45deg (Z-axis). and on hover, im translating cards' Z 20px to have that elevation. with proper easing.

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 👇

CSS Trick 🖼️ You could take the resize trick from last week and use it to create one of those sliding image components 👀 CSS only, JavaScript to enhance later 🤓 Put an image in each panel and make them position: absolute. They can use a container query unit for their size 🫶 img { position: absolute; width: 100cqi; // Make them the container width 🤙 } .panel:last-of-type img { right: 0; } The rest of the trick from last week was using display:grid with grid-template-columns. Then we have a resizable element inside the first column 😎 .panels{ display: grid; grid-template-columns: auto 1fr; 👈 } .resizer{ max-width: 100cqi; overflow: hidden; resize: horizontal; 👈 } Where does JavaScript come in? To progressively enhance the thing with keyboard controls ✨ Not 100% sure of the pattern for that though. Feels like it should be a button that you can toggle into resize mode and then use left/right to resize 🤔 Anyways, CodePen.IO link below! 👇

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! 👇

BREAKING: DeSantis hints that he might veto a legislative tax package that includes sales tax relief over property tax relief "Any Florida-last tax package is going to be dead on arrival. We are not going to kneecap our ability to provide you property tax relief just so we can give a little bit of a benefit to Canadian tourists. That is not going to happen. You can take that to the bank." "Is there anyone here that would prefer one quarter of one penny relief to property tax relief?" "I've never seen anything proposed that has so little buy-in. People are not clamoring to give Canadian tourists a tax break."

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! 👇
