What is the difference between CSS Grid and Flexbox?

Flexbox is engineered exclusively for 1-dimensional layouts (a single row OR a single column), whereas CSS Grid is designed for complex 2-dimensional layouts (rows AND columns simultaneously). Use Flexbox for micro-components like navbars, and Grid for macro page structures.
