A working reel of the animation, interaction and performance craft behind Beyonder builds. Drag it, hover it, scroll through it. Every effect is measured, not just decorated.
Four positions we hold, not as slogans but as constraints we design against.
An animation should answer a question the interface just raised: where did this element come from, what changed, what happens if I let go. If it doesn't answer one of those, it's noise wearing a nice easing curve.
Every frame gets 16.6 milliseconds. Layout and paint eat that budget fast; transform and opacity barely touch it. We spend the budget on the two or three moments that matter and leave the rest alone.
Nobody compliments a button for feeling right. They just keep clicking. The animations people do notice and mention are usually the ones we'd cut in review.
If someone's system asks for reduced motion, that's not a suggestion to soften animations, it's an instruction to remove them. We build that switch first, then decide what deserves to move.
Grab the strip below and pull. Everything in it runs on the same handful of GPU-friendly properties.
This line traces actual time between animation frames in your browser, right now, next to everything else on this page.
transform and opacity skip layout and paint entirely. Everything else, top, left, width, margin, forces the browser to recompute the page before it can even draw.
/* layout + paint, avoid */ .card:hover { top: -8px; width: 320px; } /* compositor only */ .card:hover { transform: translateY(-8px); }
It promotes an element to its own GPU layer right before a heavy transition. Leave it on permanently and you're paying memory rent on elements that never move.
We start every effect from an IntersectionObserver entry, not from page load. Elements below the fold cost nothing until they're actually seen.
prefers-reduced-motion is checked once, in JavaScript, and toggles a single class on the body. Every animation on this page listens to that class, no exceptions.
This section doesn't animate. That's on purpose, and it's the same rule we apply on client work.
Motion earns a place in onboarding, status changes and anything where cause and effect needs a visible thread. It has no business in a data table, a checkout form, or anywhere someone needs to scan fast and move on.
Parallax and large-scale scroll effects can trigger real physical symptoms for people with vestibular disorders. That's not an edge case to patch later, it's why prefers-reduced-motion exists as an operating-system setting rather than a design nicety.
On a slow connection, every animated asset competes with the content for bandwidth. A heavy animated illustration rarely earns its weight against a user on three bars of signal.
This flips reduced-motion behaviour site-wide. Reveals resolve instantly, the ticker stops, the cursor returns to default. Nothing above breaks, it just stops moving.
We score a motion pass the same way we score any interface change: load speed, attention retained, outcome moved.
