Probably old news now, but the CSS View Transition API is SUPER cool! Entry/exit layout animations like this used to be super complicated or require giant libraries. Now it's like 2 lines of JS, and a few lines of CSS if you want to customize the animation. Amazing! 🤯

yes! And here's a demo without the performance hit of using flushSync

flushSync is fine. This is the exact type of thing it is designed for. Actually in this case it may even be faster. When startViewTransition is called it freezes the DOM to take a snapshot. Flushing synchronously reduces the time the page is frozen because updates occur immediately rather than waiting unnecessarily.

Super clean. I immediately tried clicking the add button before the current transition had finished, finding that it then ignores that click. Limitation of freezing the DOM, or is there a way to stack the transitions?

Yeah it’s a limitation of the current API but I think the spec authors are aware of it so hopefully it’ll get better eventually

Is using the "flushSync" recommended for lists?

In this case it’s required for the view transition to take effect. The DOM updates have to occur inside that callback

I used my holiday break to develop my new portfolio; depending on your browser it's 95% powered by the newest css techniques like scroll driven animations and view transitions! 💪 If you see the 🦖, it's (at least partly) powered by GSAP backup animations 😅

Clay's transition API is starting to shape up. It's modeled on the simplicity of CSS transitions (i.e. just specify property, duration and tween function, the rest is automatic) but with the ability to override the tween function so you can do whatever you want, frame by frame.

Thermites used to require 7 hits to kill a Titan, but now it's just 1 to the head or 2 to the body. Feels like an actual anti-tank grenade now. #Helldivers2

Yunjin talking about the lyrics of "So Cynical (Badum)" and singing the original verses of the song she wrote "It's cool to not care, but in my eyes I feel like, why don't you say that you like something. If you like something, then you should say it instead of acting like you don't care. Sometimes it's cool to be nonchalant, but I think it's also important to be transparent especially about the positive things. So if you like something—I want to be honest about emotions, instead of going through social media and only letting red hearts and double clicks being your way of emotional connection" "You know, I also used to be super cynical and I used to also hide my emotions, but you (FEARNOTs) changed that for me, you know? Like, you make me want to be more honest about my emotions, and you make me feel like I'm worthy of love and I'm deserving of love."

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!

AWESOME NEWS! We now have a new feature on the earthquake program that my viewers are going to be mind blown to see. THE MOON, its phases and closeness / distance from Earth! This data was a feature on the old earthquake program I used to use, but now it looks like a real moon, and orbits earth when I want. I can turn it off or on at a whim, and show it when necessary!!! Super cool stuff Grok is doing!

Future CSS && UI Tip! ⚡️ You could use View Transitions to create those word carousel-type effects 😍 span:nth-of-type(2) { view-transition-name: swap; } ::view-transition-old(swap) { animation-name: slide-down; } ::view-transition-new(swap) { animation-name: slide-up; } How To 1. Create a paragraph split into spans 2. Set an interval in JavaScript that swaps out the accent word 3. Set a view-transition-name on the accent word and the last span Then you've got a responsive word carousel with View Transitions 🤙 Words and inspiration from work louder®'s home page. Had to see if this API could do it and it ended up raising a bug for the web platform! 💪 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! 👇

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. But, they aren't! CodePen.IO link below! 👇 cc Aaron Stezycki

👉 Lemme show you how I abuse the browsers new "view transition" API to get a kind of auto-animate or magic-move situation (like in my laracon slides) It's so unbelievably rad to me. If you've ever tried to manually transition a list item removal or something, you know how flip-dippin hard it is, and this makes it caaaaakeeeeeee 👇

Implemented infinite scrolling!! it was surprisingly easy 😇 With Unity it would have been super difficult, like more than a week of work. Been there done that ... Now it's down to a few lines of code. Great for app developers! Also reworked the sidebar using grouping 😊 #visionOS

A visual comparison of HTML-in-Canvas vs rasterizing DOM to a canvas texture (side-by-side below, compare average capture times) Existing approaches to pull web content into canvas are slow and lossy: - Animations glitch, or don't play at all - CSS replication is imprecise - Clogs up the main thread, other animations lag HTML-in-Canvas (texElementImage2D) lets the browser's own compositor map CSS layouts, animations, and transitions precisely into canvas/WebGL textures — one native call instead of thousands of JS style reads. It's currently available behind an experimental Chrome flag. Really cool, and I can't wait for it to become mainstream.

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!
