  3. Apply the Tailwind utilities and inspect the result at multiple viewport widths.
  4. Add interaction, dark mode, RTL, or accessibility states when the component needs them.
  5. Refactor repeated markup into a reusable component only after the visual rule is understood.

10 practical examples

  1. Apply Built-in Animations to a course website and explain the decision you made.
  2. Apply Built-in Animations to a online store and explain the decision you made.
