CSS Quiz — Flexbox, Grid, Specificity & Layouts
CSS mastery goes far beyond styling text. Understanding the cascade, specificity, flexbox vs grid trade-offs, stacking contexts, and CSS custom properties is what makes UIs truly polished and maintainable.
Strong CSS skills are highly valued — poorly written CSS is a common source of visual bugs and maintenance debt. Frontend roles expect you to own layouts without relying entirely on a UI library.
