Personality

Spring
cubic-bezier(0.34, 1.56, 0.64, 1)

Overshoots the target, then settles. The most human easing. It says: "I arrived enthusiastically."

Drama

Heavy Spring
cubic-bezier(0.22, 1.8, 0.36, 1)

Massive overshoot. For moments that matter. Hero reveals, modal entries, the thing you can't miss.

Calm

Critically Damped
cubic-bezier(0.4, 0, 0, 1)

Maximum smoothness, zero bounce. The "I'm in control" curve. Scroll transitions, page morphs, confident deceleration.

Elastic

Snap-Through
cubic-bezier(0.68, -0.55, 0.27, 1.55)

Pulls back before launching. The slingshot. For toggles, mode switches, state changes with attitude.

Urgency

Staccato
cubic-bezier(0.9, 0, 0.1, 1)

Alarm mode. Sharp entry, sharp exit. No ease. Binary. Something demands attention now.

Warning

Whip
cubic-bezier(0, 0.9, 0.1, 1)

Alarm mode. Explosive start, abrupt stop. The motion equivalent of slamming the brakes.

MOTION IS THE MESSAGE

Every transition has a curve. Every curve has a personality. Ease-out says "confident." Spring says "playful." Linear says "machine."

Static sites are documents. Kinetic sites are organisms. The motion is not decoration — it's the voice. How an element enters the viewport tells you whether it's whispering or shouting.

Alarm mode doesn't add motion. It redirects it. The same energy that was playful becomes urgent. Springs become staccato. Overshoot becomes shake. White becomes red.

Spring

Overshoot and settle. The most human easing. tension: 300, friction: 20. It says "I arrived enthusiastically."

motion / physics / warm

Critically Damped

Smooth arrival, zero bounce. The physicist's choice. No drama. Maximum elegance. Opacity fades, page transitions.

motion / minimal / calm

Ease-out

Decelerate into rest. Confident arrival. The cursor moves; the element follows — but slower, deliberately, arriving after you've already looked away.

motion / confident / fundamental

Staccato

Alarm mode only. Sharp in, sharp out. Binary motion. Something demands attention. Red enters the monochrome. Warning without panic.
