About the border radius generator
How this tool works
Border-radius values are simple, but asymmetric corners are still tedious to build by hand. This tool keeps the controls visual and copy friendly.
It is a lightweight helper for interface polish, especially when one component needs a more intentional or branded corner treatment.
Where it is useful
The preview is useful because unusual corner combinations are much easier to evaluate visually than by reading the raw shorthand alone.
It also fits neatly beside the other small design helpers in this family, which often get used during the same styling pass.
- Tune card and button corners without trial and error.
- Create more distinctive asymmetrical UI shapes.
- Copy a clean border-radius shorthand into your stylesheet.
