Fixed this small bug in Linear’s app today which I often see in other apps as well. Here’s a small before/after. The issue: When you open a popover inside a modal (think a custom select), clicking outside the popover to close it also closes the modal. The desired behavior is to close the select on click outside while keeping the modal open. This often happens because custom dropdowns or select components are rendered in a portal. The modal then treats the interaction as an outside click because, technically, the dropdown isn’t inside the modal in the DOM, it’s rendered elsewhere via a portal. The fix depends on your setup, whether it’s Radix/Base UI, fully custom etc. But since you now know the cause of it, you can ask your agent to fix it for you!

Don’t animate keyboard-initiated actions. As an example, I use Raycast hundreds of times a day. If it animated every time I opened it, it would make it feel slow, delayed, and disconnected from my actions. But there’s no animation at all. That’s the optimal experience.

Made this interaction of Linear’s dithered logo for our latest release. It’s using canvas with a lot of tiny dots. There’s an invisible circle around the cursor. Any dot inside it gets pushed outward with a cubic falloff so it’s gentle on the edges, and strong at the center.

You might’ve seen this bug before where the hover state keeps flickering. The fix is to separate the trigger from the effect. Listen for hovers on the parent, but animate a child element instead. This ensures that the hover area stays consistent.

There’s a fun little easter egg in my animation course: As enrollment gets closer to closing, the butter cube melts more with each hour by animating the svg paths.

One of my favorite things from the new Linear homepage are these side drawers which you can open to get some info about a specific feature. Made with Base UI’s dialog component and some ease-out.

Hover transitions seen tens, maybe even hundreds of times a day can make your interface feel slower. Make them snappy by removing the transition altogether.

A high-ROI tip from is to record your animations and play them frame by frame to spot imperfections you wouldn’t otherwise notice. These hidden imperfections are what makes an animation feel off, even though it looks alright at first glance.

Keep your animations fast. A faster-spinning spinner makes you think the app loads faster. It improves perceived performance. The same applies to user-initiated actions. Use `ease-out` to make them feel snappy and responsive.

Trying some stuff out and I kinda like that the button changes color depending on the state that it's in?

Given how impressed I was with Cursor’s Thermo-Nuclear Code Quality Review skill, I decided to create a similar one, but specifically for animations. /review-animations to review, and /emil-design-eng to build animations. They complement each other well

A demo of the animations[.]dev skill file using Claude Code. It can review your animations, suggest improvements, and basically answer all your motion-related questions based on my experience gathered over the years.

A few interactive demos from a recent addition to my animation course: A six-part module on SVG animations where you’ll learn about the coordinate system, path syntax, stroke properties, and more. We’ll end up building some of the illustrations from the course’s homepage.
