The Versatility of `gap-*` (Flexbox & Grid)

As highlighted in the "Gotcha", gap-* utilities are very handy for creating space *between* elements and work well with both Flexbox and Grid layouts.

Here, gap-4 creates a 1rem gutter both horizontally and vertically between items when they wrap to the next line. This is simpler than trying to manage margins on individual items.

With CSS Grid, gap-4 creates a 1rem gutter between grid columns and rows. This consistency makes gap-* a preferred method for spacing in many layout scenarios.

Recap on "Gotcha" and `gap-*`:

While justify-* has its place for distributing items along a flex container's main axis (e.g., justify-between for full-width navs), gap-* is often the simpler, more direct tool for creating consistent spacing *between* elements in both Flexbox and Grid. Understanding this distinction helps avoid confusion and write cleaner layout code.
