Overview

The CSS Border Radius Generator helps you create elements with rounded corners. You can control the radius of each corner individually (top-left, top-right, bottom-right, bottom-left) or all at once, and see a live preview of how it affects a sample element. The tool then generates the necessary `border-radius` CSS.

Use Cases

  • Creating rounded buttons, cards, and other UI elements.
  • Designing organic or uniquely shaped containers.
  • Achieving specific corner effects like a single rounded corner or pill shapes.
  • Learning how the `border-radius` CSS property works with its shorthand and individual corner syntaxes.
  • Quickly generating CSS for complex rounded shapes.

How It Works

Use the input fields or sliders provided for "All Corners" or for each of the four corners: Top-Left, Top-Right, and Bottom-Right, Bottom-Left. You can also select the unit (px or %). As you adjust these values, the live preview of a sample box will update to show the effect. The tool will generate the corresponding `border-radius` CSS rule, which you can then copy.

Tips for Better Usage

  • You can use different units like `px`, `%`, or `em` for border-radius values. The tool supports px and %.
  • To create a circle from a square element, set the border-radius to 50%.
  • For pill-shaped buttons, use a large radius value (e.g., `9999px`) on a rectangular element.
  • The `border-radius` property can accept one, two, three, or four values to control all corners or specific combinations.
