About this Tool

Frame your work. Generate CSS border code for solid, dashed, dotted, and double borders. Adjust radius and color to create the perfect box.

Borders define structure. While basic, `border` and `border-radius` are the building blocks of buttons, cards, and inputs. This tool lets you visually tweak parameters until they 'feel' right, then gives you the code.

  1. Adjust width, style, and color.
  2. Set the border radius (rounded corners).
  3. Copy the generated CSS.
  • Designing a call-to-action button with rounded corners.
  • Creating a circular profile picture frame.
  • Adding a dashed outline for a 'drop zone'.
  • Live Preview: See the box change instantly.
  • Independent Corners: Round just one corner or all.
  • Modern Styles: Create pill shapes or circles easily.

It generates a standard CSS string: `border: [width] [style] [color]; border-radius: [value];`.

How do I make a circle?

Set the width and height to be equal (a square), then set `border-radius` to 50%.

Can I have different borders on each side?

Yes, CSS supports `border-top`, `border-left`, etc., though this tool generates a uniform border for simplicity.

What is 'double' style?

It draws two parallel lines. You need a width of at least 3px to see it clearly.
