CSS Grid and Flexbox are both powerful layout systems, but they serve different purposes. Understanding when to use each one is key to writing clean, maintainable CSS.

Flexbox: One-Dimensional Layouts

Flexbox excels at distributing space along a single axis. Use it for navigation bars, card rows, centering content, and any layout that flows in one direction.

Grid: Two-Dimensional Layouts

CSS Grid shines when you need to control both rows and columns simultaneously. Use it for page layouts, image galleries, dashboards, and complex arrangements.
