Frequently asked

?

Can I use both on one page?

Yes — that's the recommended approach. Grid for the page-level layout (header, sidebar, main, footer). Flexbox inside each region for the component-level arrangement (nav items, card content).

?

Is flexbox obsolete now?

No. Flexbox is still the simpler choice for one-dimensional arrangements. Grid is overkill for a nav bar; flexbox is overkill for a 12-column page layout. Use the right tool for the shape of the problem.
