The 4-point grid, and why 16 makes it easy
The browser already gave you a base — 16px — and 16 divides by 4 and by 8. Pick one as your spacing unit, size and space everything in multiples of it, and let the tool do the arithmetic. Tailwind already did: its unit is 4px, and you can change it in one line.
