Transition specific properties, not `all`
List intended transition properties so unrelated later style changes do not animate accidentally.

Bad example
Old codescss
| 1 | .btn { transition: all 0.3s ease; } |
Explanation (EN)
all can animate an unrelated property added later and create unexpected layout motion.

Good example
New codescss
| 1 | .btn { transition: background-color 0.3s ease; } |
Explanation (EN)
Only the intended color change receives this transition.

Notes (EN)
For a component transition, list the properties intended to animate and verify hover/focus/disabled states and reduced-motion behavior.
Exceptions / Tradeoffs (EN)
all can be deliberate in a small controlled effect; performance cost depends on the properties that actually change, not a claim that every property is continuously polled.
