Be ready to compare utility-first vs design tokens, explain specificity issues, and describe when you would extract components from noisy markup.
Going deeper
In production utility-first CSS work, Interview essentials 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 interview essentials on a real project.
Interview prep
- Name two risks of utility-heavy markup.
Unreadable HTML and cascade conflicts when utilities fight component CSS or load order shifts.
- How do you keep bundle size sane?
Generate only used utilities, document tokens, purge in CI, and avoid duplicating tokens as raw hex in every class.
