Particles

Full motion specification

How the movement works

Use it to add celebration or liveliness, in place of confetti or sparks.

1. 0184 particles, emitted from the bottom centre (horizontal centre, 20 px above the bottom edge).
2. 02Initial velocity: ±190 px/s horizontally, 250–400 px/s upward. Gravity 470 px/s² (parabolic paths).
3. 03Each particle repeats with a period of 2.35 s or about 1.57 s, with a random start offset (fixed seed, so every run looks the same).
4. 04Lifetime up to 1.5 s: fade in over the first 0.06 s, fade out over the last 30%. Scale 1.15→0.7.
5. 05Shapes are circles, squares and triangles (size 5–11 px) in blue, coral, yellow and mint, spinning at up to ±4.5 rad/s.
