- Read the lesson concept.
- Open the playground — reset if you get lost.
- Change one utility group at a time (spacing, then flex, then color).
- Use browser DevTools to confirm which rule wins in the cascade.
Going deeper
In production utility-first CSS work, Playground workflow matters when documents, stylesheets, or apps must stay maintainable across teams and releases—not only in isolated demos.
Common pitfalls
Watch for copy-paste configs, skipping validation or tests, and mixing concerns (structure vs presentation vs behavior) in one layer.
Practice
- Apply one technique from this lesson in the playground.
- Write one interview-style sentence explaining when you would use playground workflow on a real project.
