Animation
What is Easing?
How an animation speeds up or slows down over its duration. Two animations can travel the same distance in the same time but feel completely different based on easing alone.
In real work
Pick the right easing: use ease-out for all entrances. Use ease-in-out for elements moving from one position to another.
How is this different from Googling it?
Google gives a definition. Prompthaus pairs each term with how it shows up in standups, PRs, prompts, and design reviews—then quizzes you until the word sticks. One term a day on iPhone.
