This lesson

This lesson teaches Playground workflow—the ideas, syntax, and habits you need before moving on in Tailwind CSS.

Config-driven utilities are how most greenfield product CSS is written today.

You will apply Playground workflow in contexts like: React/Vue/Next apps, marketing sites, design systems, and rapid prototypes where consistency and speed matter.

Read the lesson, edit HTML/CSS in the playground, press Run to preview, then answer the lesson MCQs.

Early in the track—complete this before layout, scripting, or architecture lessons that assume these basics.

Get the most from each lesson’s live editor with a deliberate loop—same habits that transfer to real projects.

Recommended workflow

  1. Read the concept section before touching code.
  2. Change one utility group at a time (spacing, then flex, then color).
  3. Resize the preview pane to test responsive prefixes.
  4. Use browser DevTools to inspect which utility wins when debugging.
  5. Reset the editor if you drift too far from the lesson goal.

Review CSS cascade if two classes seem to conflict—Tailwind uses layered specificity by design, but custom CSS can still override utilities.

Self-check

  1. Why change one utility group at a time during learning?
  2. What DevTools panel confirms a Tailwind class is applied?

Challenge

CDN smoke test

  1. Open the playground and confirm Tailwind classes apply (try bg-indigo-100 on a div).
  2. Add hover:bg-indigo-200 and hover the preview.

Done when: preview updates without a separate stylesheet file.
