About the CSS Border Radius Generator
Adjust all four corners together, or unlock them to set each one independently. Switch on elliptical mode to control horizontal and vertical radii separately and you can shape the smooth organic blobs used across modern landing pages.
The preview scales with the values you choose so you always see the real shape, and the generated declaration uses shorthand wherever it is valid to keep your CSS tidy.
