Build a three-tier pricing row using only tu- utilities and token variables. No third-party framework classes.
Going deeper
In production utility-first CSS work, Capstone: pricing layout 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 capstone: pricing layout on a real project.
Challenge
Highlight a plan
- Add
tu-borderin a stronger color on the middle card only. - Add a “Popular” badge with utilities (no new component file).
Done when: middle tier is visually emphasized without breaking the grid.
