Answer
Flexbox is primarily one-dimensional, while Grid is two-dimensional. • Flexbox distributes items along a main axis and cross axis. • Grid defines rows and columns that items can occupy. • They can be combined; neither replaces the other.
💡 Simple Example
.page { display: grid; grid-template-columns: 16rem 1fr; }
.actions { display: flex; gap: .5rem; }
