Flexbox is best for a single row or column of items that need to align, distribute or reorder. Grid is best for two-dimensional layouts — rows and columns at once — including responsive card grids using repeat(auto-fit, minmax(...)), which wraps to fewer columns on narrow screens with no media queries. Everything runs client-side — this is a static CSS generator, not a live editor for your own page. For shadows and glass effects, try the CSS Shadow Generator or Glassmorphism Generator.

Flexbox & Grid generator FAQ

Flexbox or Grid — which should I use?

Flexbox suits one-dimensional layouts (a row or column that aligns/distributes items). Grid suits two-dimensional layouts — rows and columns together.

What does auto-fit minmax do?

repeat(auto-fit, minmax(200px, 1fr)) creates a responsive grid that fits as many columns as comfortably fit the minimum width, wrapping to fewer on narrow screens — no media queries needed.
