What it means
A visible card grid is one use, but an invisible grid can also align headings, images and text across different sections. The underlying structure helps a varied page feel connected. It can be implemented in different ways; a visual grid does not establish that the site uses CSS Grid.
Use it in practice
Choose columns that fit the content and reduce them when space becomes limited. Align neighboring sections intentionally rather than forcing every element into an identical box.
Watch out for
Do not keep too many columns on a phone. Fixed-height cells can truncate useful text or create unnecessary gaps.
