CSS Grid vs. Flexbox: Two-Dimensional vs. One-Dimensional

Modern web layouts combine two powerful CSS layout engines:

CSS Flexbox (One-Dimensional)

• Arranges items along a single axis (either row or column).
• Ideal Use Cases: Navigation bars, button groups, icon-and-label alignments, tag lists. Content dictates size.

CSS Grid (Two-Dimensional)

• Simultaneously controls both rows and columns.
• Ideal Use Cases: Overarching page layouts, complex dashboard card arrangements, magazine-style editorial features. Grid dictates size.
