  2. Build a very small HTML example before placing it inside a large component.
  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 grid to a course website and explain the decision you made.
  2. Apply grid to a online store and explain the decision you made.
