What is CSS Border Radius Generator?
CSS Border Radius Generator is an interactive design tool for creating border-radius CSS declarations visually instead of writing complex eight-value border-radius shorthand by hand. Modern CSS border-radius supports up to eight values when using the slash notation four horizontal radii slash four vertical radii enabling not just simple uniformly rounded rectangles but also organic asymmetric blob shapes pill buttons capsule shapes egg shapes leaf-like forms and custom design tokens for component libraries. The eight-value syntax border-radius top-left top-right bottom-right bottom-left slash vertical equivalents is powerful but rarely used because it is difficult to visualize and memorize. This generator provides a live visual shape with eight individual draggable handles one at each corner horizontal and one vertical to sculpt the exact form in real time. Common shape presets are available with one click perfect circle standard rounded corners smooth pill button iOS-style soft rounded corners squircle Squircle aesthetic organic blob and asymmetric shapes. You can also lock all corners together for uniform rounding or unlock them for custom asymmetrical designs. The tool outputs not just the border-radius property but also the older -webkit-border-radius and -moz-border-radius prefixes for legacy compatibility along with an interactive visual comparison showing before-and-after shape preview to evaluate the design impact.
