Flexbox vs CSS Grid is Not A Thing
Too Long; Didn't Read
There is NO flexbox vs. CSS Grid: It’s just flexbox and CSS grid. Both should be used in conjunction. Flexbox works in a single axis and has a cross-axis that makes it workable in 2-dimensional structure. CSS grid provides a grid layout. So it seems natural to use it where you have multiple images, or card-like components stacked in a grid-like structure. By choosing either of them for all purposes, you force yourself to think of a row as a grid or a grid as two separate dimensions.
