animations that level up user experience

good animations fly under the radar. they guide attention, confirm actions, and add context without fighting the content

principles to avoid overdoing it

• purpose

  every movement should answer one question: what does the user gain here? taste is choosing the smallest motion that still communicates clearly

• timing

  150–250ms for microinteractions and 300–400ms for page transitions or bigger changes. calibrate by feel: if you notice it, it's probably too slow

• distance-based

  elements that travel farther can take slightly longer, proportional to distance (e.g. a button that moves 10px will take 100ms, a button that moves 20px will take 200ms). map motion to meaning, not flair

• easing

  use ease-out for quick entrances and ease-in for exits; for natural vibes, prefer cubic-bezier curves. taste lives in these curves — subtle over flashy

hover, focus, and pressed that actually communicate state

• hover

  bump contrast a bit or add a soft elevation (no layout shift) to indicate the button is interactive. tiny changes feel more trustworthy than big jumps

• focus

  use a visible outline and a short transition (120–160ms) to indicate the button is focused. clarity beats decoration

• pressed

  a tiny compression (scale 0.98) with a quick bounce back to confirm the click to indicate the button is pressed. snappy in, calm out

instant feedback on actions

• optimistic UI

  for fast interactions, flip the button to "saved" with a short animation; on failure, revert with a tiny shake (2–3px). confirm success quickly; make errors noticeable but not dramatic

• loading

  prefer skeletons over spinners when there's structure; keep shimmer to 600–800ms per cycle so it doesn't scream at the user. taste is reducing stress, especially during wait time

transitions that preserve context

• source and destination

  when a card becomes a page, move and scale from the card's position (match-move). show where things came from and where they go

• hierarchy

  animate backdrop and content separately to avoid "teleporting" the user to a new position. keep narrative continuity

motion accessibility

respect prefers-reduced-motion. reduce trajectories and keep only quick fades — or no animation — when the user asks for less motion. taste includes respecting user comfort

quick pre-ship checklist

• does the animation help understand what just happened?
• under 400ms (except narrative moments)
• works with prefers-reduced-motion
• keeps contrast and readability during movement

apply these principles to the most frequent elements (buttons, lists, forms). tiny consistent improvements create a smoother experience without yelling "look at me"
