Cursor Click Ripple
An animated cursor moves to a target element, performs a click with visual depression, and emits expanding ripple rings from the click point.
How It Works
Three sequential phases driven by a single GSAP timeline:
- Move: eased cursor translation from entry point to the target element's center
- Click: scale depression on both cursor and target (yoyo: shrink then return)
- Ripple: expanding circles radiate outward from the click point with fade-out. 1–3 staggered rings amplify the click feedback
Use a GSAP timeline because the phase ordering (move → settle → click → ripples) is exactly what timelines express cleanly.

CSS
Position cursor at the entry point. Button sits at its final position. Ripples are at the click-target center with scale: 0 and opacity: 0 so they hold invisible until the timeline trigger:
.scene {
position: relative;
width: 100%;
height: 100%;
}
.target-button {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
/* ...button styling (background, color, font from project tokens) */
}
.cursor {
position: absolute;
left: 10%;
top: 80%; /* entry corner */
pointer-events: none;
z-index: 999;
}
.ripple {
position: absolute;
left: 50%;
top: 50%; /* click target center */
width: 100px;
height: 100px;
border-radius: 50%;
border: 2px solid {rippleColor};
transform: translate(-50%, -50%) scale(0);
opacity: 0;
pointer-events: none;
}
GSAP Timeline
Build a paused timeline. Register it on window.__timelines with the same key as data-composition-id on the scene root. All tuning values are named constants — see How to Choose Values below.
<script src="https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js"></script>
<script>
window.__timelines = window.__timelines || {};
const tl = gsap.timeline({ paused: true });
// MOVE_DUR, MOVE_EASE, CLICK_AT, PRESS_DUR, CURSOR_PRESS_SCALE, TARGET_PRESS_SCALE,
// RIPPLE_AT, RIPPLE_DUR, RIPPLE_SCALE, RIPPLE_STAGGER, RIPPLE_EASE
// — all named; values per How to Choose Values.
// Phase 1 — Move cursor to target center (eased, not linear)
tl.to(
".cursor",
{
x: TARGET_X,
y: TARGET_Y,
duration: MOVE_DUR,
ease: MOVE_EASE,
},
0,
);
// Phase 2 — Click: cursor + target depress together, then return
tl.to(
".cursor",
{
scale: CURSOR_PRESS_SCALE,
duration: PRESS_DUR,
ease: "power2.in",
yoyo: true,
repeat: 1,
},
CLICK_AT,

tl.to(
".target-button",
{

ease: "power2.in",
yoyo: true,
repeat: 1,
},
CLICK_AT,
);
// Phase 3 — Ripple burst, N rings staggered from the click point
tl.set([".ripple-1", ".ripple-2", ".ripple-3"], { opacity: 1 }, RIPPLE_AT);
tl.to(

</script>
How to Choose Values
-
MOVE_DUR — cursor travel time from entry to target, in seconds
- Range: 0.4–1.0 s
- Effects: short feels darting; long feels deliberate / "considered click"
- Constraints: must end before
CLICK_AT— otherwise the click fires while the cursor is still moving and reads as a misclick - Reference: examples/cta-orbit-collapse.html uses 0.5 s
-
MOVE_EASE — easing family for the move tween
- Discrete choice. Options:
power2.inOut— symmetric, calm; good for "the user thoughtfully moves the cursor"back.out(<n>)— overshoot landing; good when the click target is a button you want the cursor to "settle onto" with a tiny visible recoil. Pair with a low overshoot coefficient (~1.2–1.4) — higher reads as cartoonishpower3.out— fast start, soft landing; good for a "decisive" move
- Reference: examples/cta-orbit-collapse.html uses
back.out(1.3)
- Discrete choice. Options:
-
CLICK_AT — time the click fires, in seconds
- Range: must be ≥
MOVE_DUR(cursor has settled); typicallyMOVE_DUR + 0.0–0.3 sof "decision pause" - Effects: zero pause reads as autopilot; >0.3 s of pause reads as hesitation
- Reference: examples/cta-orbit-collapse.html clicks 0.2 s after the cursor settles
- Range: must be ≥
-
PRESS_DUR — half-duration of the depression (the yoyo runs twice this)
- Range: 0.06–0.12 s
- Effects: short feels crisp; long feels mushy
- Constraints: total press =
2 * PRESS_DUR; must finish before the next scene phase needs the cursor / target back at normal scale - Reference: examples/cta-orbit-collapse.html uses 0.08 s
-
CURSOR_PRESS_SCALE / TARGET_PRESS_SCALE — how far each compresses during the click
- Range: cursor 0.80–0.90; target 0.92–0.97
- Effects: smaller numbers = stronger "this click counts" feel; values close to 1 read as a gentle tap
- Constraints: cursor compresses MORE than the target — the cursor is the actor, the target is the recipient
- Reference: examples/cta-orbit-collapse.html uses cursor 0.85 / target 0.95
-
RIPPLE_AT — when the rings start expanding, in seconds
- Range:
CLICK_AT + 0.0–0.08 s - Effects: simultaneous with the press feels causal; slight delay feels acoustic ("the click happens, then the wave radiates")
- Reference: examples/cta-orbit-collapse.html starts the ripple at
CLICK_ATexactly
- Range:
-
RIPPLE_DUR — how long each ring takes to fully expand and fade
- Range: 0.5–1.0 s
- Effects: short rings feel sharp; long rings feel like a soft sonar
- Constraints: must complete before any phase that depends on the ring being gone (e.g. a screen wipe)
- Reference: examples/cta-orbit-collapse.html uses 0.7 s
-
RIPPLE_SCALE — final scale of each ring before it fades
- Range: 3–6
- Effects: 3 keeps the ring near the click site; 6 lets it sweep the surrounding area
- Constraints: if the ring would exit the visible frame before opacity reaches 0, lower the scale or shorten the duration
- Reference: examples/cta-orbit-collapse.html uses 5
-
RIPPLE_STAGGER — delay between consecutive rings
- Range: 0.06–0.12 s (or 0 for a single ring; see Variations)
- Effects: below ~0.06 s reads as one thick ring; above ~0.12 s reads as separate events
- Reference: examples/cta-orbit-collapse.html uses a single ring (no stagger)
-
RIPPLE_EASE — easing family for the expansion
- Discrete choice. Options:
power2.out— fast start, soft tail; the standard "ping" feelpower3.out— even sharper attack, longer tailexpo.out— almost-instant expansion with a long quiet fade; reads as a strong, distant pulse
- Reference: examples/cta-orbit-collapse.html uses
power2.out
- Discrete choice. Options:
-
TARGET_X / TARGET_Y — pixel offset of the click target from the cursor's CSS-laid origin
- These are layout-derived, not creative knobs — they must match the visual centroid of the actual click target. A 4 px miss reads as missing the button
- Reference: examples/cta-orbit-collapse.html targets the white button at
CENTER_X + 130, CENTER_Y + 15
Variations
- Single ring — keep one
.rippleelement, drop the stagger; reads as more elegant when the rest of the scene is busy - Keyframed attack-decay — replace the simple expand-and-fade with a
keyframesblock that ramps opacity 0 → peak → 0 across the duration; gives a clearer "energy radiates and dissipates" envelope (used in examples/cta-orbit-collapse.html) - Multi-ring expanding pulse — 3 rings with 0.08 s stagger feels richer when the click is the climactic moment of the scene
Key Principles
- Move before click: trigger the click only after the move tween has settled — clicking mid-motion reads as unintentional
- Synchronized depression: cursor + target depress at the same
positiontime with the same duration (and both yoyo back) - Ripple from click point: ripples expand from the exact click location (the button's visual center), not from any element's bounding-box origin
- Subtle scale: cursor compresses more than the target — see
CURSOR_PRESS_SCALE/TARGET_PRESS_SCALE - High z-index cursor: cursor renders above all content for the entire sequence
Critical Constraints
- Timeline must be paused:
gsap.timeline({ paused: true }). Never calltl.play()— HyperFrames seeks the timeline frame-by-frame deterministically - Registry key =
data-composition-id:window.__timelines["<id>"]must match thedata-composition-idon the scene root exactly immediateRender: falseon the ripple expand: holds the initial state (scale: 0,opacity: 0) until the click moment, otherwise the tween pre-renders and the rings appear at the wrong size at t=0- Finite duration: verify
tl.duration()matches the scene'sdata-duration pointer-events: noneon cursor + ripples: they're purely visual; never block underlying interactivity (matters for hover-able exports)- No CSS transitions / animations: all motion lives in the GSAP timeline so seek stays deterministic
Combinations
- orbit-3d-entry.md — when the click is the pivot that collapses orbiting elements toward the cursor's target
- center-outward-expansion.md — the click can be the trigger for an outward burst from the click point
- press-release-spring.md for stronger physical feel on the target button
- scale-swap-transition.md for the button's state change after click (button morphs into success state, next view, etc.)
Pairs with HF skills
