Square by default
Every Tailwind radius is set to 0, so rounded-lg still draws a square corner. Buttons, fields, cards, menus and modals are all square.
Three exceptions
| Class | Where | |
|---|---|---|
rounded-window · rounded-window-inner | Product windows and screenshots (12px / 6px) | |
| Tag | rounded-full | Tags, badges, toggles, dots and avatars |
| DayWeek | rounded-full | Pills inside compact groups: theme switch, segmented controls, filter chips |
Do
Calls to action stay square.
Don’t
Don’t round a standalone button.
