Using `gap-*` and Understanding the `justify-*` Gotcha

Using gap-4 for simple spacing between items (row)

Item 1
Item 2
Item 3

gap-4 adds a consistent 1rem space *between* flex items, horizontally here.

Gotcha: `justify-*` vs `gap-*` in `flex-col`

The "Gotcha" is that justify-* classes control spacing along the main axis . For flex-row (default), this is horizontal. For flex-col , it's vertical. gap-* is often simpler and more direct for adding space *between* items, regardless of the main axis distribution.

justify-between in flex-col :

Top Item
Middle Item
Bottom Item

With flex-col justify-between and a set height, items are pushed to the start, middle, and end of the container's vertical axis. This might not be what you want if you just need consistent spacing *between* items.

gap-4 in flex-col (Often Simpler):

Item A
Item B
Item C

With flex-col gap-4 , a 1rem space is added *between* each item vertically. The container's height grows with content + gaps. This is often more intuitive for inter-item spacing.

Key Takeaway: If you want space *between* items, gap-* is usually the most straightforward approach for both flex-row and flex-col . Use justify-* when you specifically need to distribute items along the entire length of the main axis (e.g., pushing items to the edges).
