Several things moving at once
=============================

Rule · bucket: judgment · severity: note · detector: none · since: v0.23.0
Section: Things to avoid
Group: Motion

Forbidden:
  A hero with a drifting gradient, a bouncing scroll arrow, a logo ticker and a pulsing "New" badge, all running together.

Instead:
  At a time, one thing moves: the one the user caused, or the one they need to notice now. Things that move as one count as one: a list reordering, `P-13`'s ambient layers on one surface.

Motion is the strongest pull on the eye a page has. Two things moving split it; four make the page restless, and the one that matters (a saved state, an error arriving) competes with decoration and loses. `G-145` is the one-dot case of this rule.
