Animation · Interaction
Words that answer.
Motion is a word arriving on its own. Interaction is a word replying to you: it leans when you hover, lands when you click, follows when you drag. On a screen, the reply is part of the type.
Ten kinds
Every event has a reply.
Each one below is live. Each also has a way in by keyboard, and with reduced motion each reply becomes a change you can see without anything moving.
Four rules for words that answer.
A reply is a promise: something happened, and the page noticed. Keep the promise small and keep it honest.
Answer what was asked
The reply should match the gesture. A hover leans, a click lands, a drag follows. Surprise is for the second visit.
Fast to start, slow to settle
Begin within a tenth of a second, then take your time coming to rest. The reader should never wait for the word.
Every gesture has a key
Anything a pointer can do, a keyboard can too. Every kind here shows its keys.
Still is an answer
With reduced motion, the word still replies, by weight or by a line, without moving.
