no support? use a thin "sentinel" element that you watch with IntersectionObserver to toggle attribute styling 🤙. if (!CSS.supports('container-type: scroll-state')) {. new IntersectionObserver(([e]) => {. root.dataset.stuck = !e.isIntersecting. }).observe(sentinel).}
CSS picture-in-picture video transition using container queries + position: sticky 🧑🍳. container { container-type: scroll-state; }.@container scroll-state(stuck: top) {. video {. translate: calc(50vw - 100%) calc(100vh - 100%);. }.}

特定箇所で横スクロールになるアニメーション🗣️. IntersectionObserverとposition: stickyを組み合わせ、特定位置で縦スクロールから横スクロールに変更するアニメーションを実装しました💁♂️. よく見るこの動き、調整が難しかったけどなんとかここまで実装できた🙌

If you want to work with `IntersectionObserver` using #RxJS, just use this function to convert it to an Observable:

Just found out an Astro's markdown feature, when displaying a markdown document you have h1 h2 etc headings automatically available in a JS object to easily display in a menu, added some IntersectionObserver magic to highlight current section in document

I'm working on a massive JS Ecosystem guide and I'm SO pleased with this little prototype. Just about 10 lines of JS (pretty much only IntersectionObserver and button events) + CSS scroll-snapping. Everything is scroll-driven 🤌🤌

just shipped a new dashboard homepage at @modal_labs!. it load in <1 second even with hundreds of graphs, using some IntersectionObserver magic with Svelte (only render graphs on the screen & prioritize + pipeline api requests). always enjoy trying new things on the web 🔘

WebGL空間上の平面をDOMのimg要素と位置連動させ、IntersectionObserverを利用して可視判定を行い、表示演出を着火させるやつをやりました。スクロール演出の実装が超カンタンになってて驚いた。

learned a new trick from the facebook source today:. to measure when DOM mutations are painted to the screen, use IntersectionObserver on document.body!. in older browsers, falls back to rAF + setTimeout 0

Spent 3 days tracking down memory leaks and got @ladybirdbrowser down from 15.8 GiB to 2.4 GiB (private) when running Speedometer 3.0 🤓📉. Main issues fixed:.- JS async function leak.- IntersectionObserver leak.- JS class field initializer leak.- Overzealous GC stack scan

Working on some new benchmarks to get Framer Motion's deferred keyframes working with scroll-linked animations. Using IntersectionObserver was the right choice for scroll-triggered animations. Cold start time for 1000 elements is 250x faster in Framer Motion over GSAP.

Like JS's `IntersectionObserver`, using CSS to track elements crossing the `ScrollPort` and applying `blurFadeIn` animation. 🔗 Source Code and References:.

Scrolly-telling with code:. 1. Place a "code editor" UI in a fixed position. 2. Add scrolling <section> elements. 3. Use an IntersectionObserver to monitor visible sections and place CSS class ".visible".4. Use :has() to target specific code lines based on the visible section.

ポートフォリオ制作の一環でhtmlとCSSで作った3DオブジェクトをCSSだけで動かしてみた. jsはあくまでアニメーション発火するためのトリガーとしてintersectionObserverだけを書いた🫡
