Border Radius Generator
A tool to adjust CSS border-radius for each corner with real-time preview.
Horizontal Radius
Vertical Radius
Use the sliders to adjust the roundness of each corner. Check "Link all corners" to change all corners simultaneously with a single slider. In "Advanced mode" you can set horizontal and vertical radii separately to create elliptical corners.
About the border-radius Property
The CSS border-radius property is used to round the corners of elements. You can set individual values for each of the four corners (top-left, top-right, bottom-right, bottom-left). Additionally, by specifying horizontal and vertical radii separately for each corner, you can create elliptical rounded corners. In shorthand notation, it is written as "border-radius: TL TR BR BL / H-TL H-TR H-BR H-BL".
