OpusDesk Hub What this tool does
Create a four-corner border-radius declaration. The controls set top-left, top-right, bottom-right and bottom-left radii in that CSS order. Uniform mode synchronizes all corners. Values are clamped to 0–100 pixels and the preview shows the current declaration.
How to use Border Radius Generator
- Prepare the input. Choose uniform or individual corner controls.
- Run or configure the tool. Adjust radii in pixels.
- Check and use the output. Copy the declaration and test it on the actual element.
How this tool works
The controls set top-left, top-right, bottom-right and bottom-left radii in that CSS order. Uniform mode synchronizes all corners. Values are clamped to 0–100 pixels and the preview shows the current declaration.
Worked example
Input: Uniform mode; radius 16
Output: border-radius: 16px 16px 16px 16px;
Limits, assumptions and interpretation
This interface exposes pixel corner radii, not percentage, elliptical slash syntax or arbitrary units.
- The real element’s dimensions can make the browser scale oversized radii.
- Clipping contents/images may also require overflow rules in the destination; this generator only writes border-radius.
