Using `space-*`, `gap-*`, and Addressing the "Gotcha"

Using `space-x-4`

Item 1
Item 2
Item 3

The `space-x-4` class on the flex container adds a 1rem (16px) margin to the left of all direct children except the first one.

Using `gap-4`

Cell 1
Cell 2
Cell 3
Cell 4
Cell 5

The `gap-4` class on the grid container adds a 1rem (16px) gap between grid rows and columns.

"Gotcha": Arbitrary Values vs. Tailwind Scale

While Tailwind allows arbitrary values, relying on them too much can break the consistency provided by its spacing scale.

Less Consistent (Arbitrary Values):

Item A (`p-[7px]`)
Item B (`p-[11px]`)

Here, `p-[7px]` and `mr-[3px]` are arbitrary. Overuse can lead to an inconsistent visual rhythm.

More Consistent (Tailwind Scale):

Item X (`p-2`)
Item Y (`p-3`)

Using `p-2`, `p-3`, and `space-x-1` leverages Tailwind's predefined scale, promoting consistency. If exact pixel values are critical and not on the scale, use them sparingly.
