Frequently Asked Questions
What Does This Tool Do?
This border-radius generator lets you visually design rounded corners for any CSS element. Drag the sliders, watch the preview update in real time, and grab the generated CSS with one click. No more guessing pixel values in your stylesheet.
How border-radius Works in CSS
The CSS border-radius property accepts values in pixels, percentages, or ems for each corner. You can set all four corners at once with shorthand (border-radius: 10px) or control each one individually. Percentages are relative to the element's dimensions, which is why 50% on a square makes a circle.
Preset Shapes and Custom Designs
Jump-start your design with built-in presets for circles, pills, and rounded rectangles. Or go wild with asymmetric values on each corner to create organic, blob-like shapes that are trendy in modern UI design.
Works With Every Modern Browser
The border-radius property is supported by all major browsers, including Chrome, Firefox, Safari, and Edge. The shorthand syntax generated by this tool is the most compatible format, so you can paste it straight into your project without vendor prefixes.
