Animation · Interaction
Words that answer.
Motion is a word arriving. Interaction is a word replying: it leans on hover, lands on click, follows a drag.
Ten kinds
Every event has a reply.
All live, all keyboard-ready. With reduced motion, each reply changes without moving.
Four rules for words that answer.
A reply says the page noticed. Keep it small and true.
Answer what was asked
Match the gesture. Save surprise for the second visit.
Fast to start, slow to settle
Begin within a tenth of a second, then settle slowly. Never make the reader wait.
Every gesture has a key
Anything a pointer can do, a keyboard can too.
Still is an answer
With reduced motion, the word replies by weight or a line.
