Details that make interfaces feel better

A list of small things I keep finding in the interfaces that feel best to use, and the ones I keep adding to my own work.

Tabular numbers in any UI that shows numbers next to each other. The default proportional widths jitter; tabular makes them sit still.

Easings that aren't ease-in-out. Most native iOS animations use a curve closer to cubic-bezier(0.32, 0.72, 0, 1). It feels less rubbery and more deliberate.

Buttons that are 36–40px tall, not 32. The hit target matters more than visual density on most pages.

Reduced-motion respect. If `prefers-reduced-motion` is set, your slideshow shouldn't auto-advance. It's two lines of code.
