How to Use

1. Configure the element type, label text, and content you want displayed inside the shaped element. 2. Adjust the border-radius sliders for each corner (top-left, top-right, bottom-right, bottom-left) and set the element's size, background color, and text color. 3. Preview the live result rendered with your exact values in the output panel. 4. Copy the generated Bootstrap 5 HTML snippet and paste it directly into your project, no dependencies beyond Bootstrap CSS.

Why Use This Tool?

Manually tweaking border-radius shorthand for asymmetric shapes is error-prone and time-consuming, this tool eliminates the guesswork by exposing individual corner controls and rendering the result instantly. The output is clean Bootstrap 5 HTML with inline styles only where Bootstrap utility classes can't express dynamic values, so it drops cleanly into any Bootstrap project. No account, no install, no build step required.

Frequently Asked Questions

What is the CSS Border Radius Generator?

It's a free browser-based tool that lets you configure per-corner border-radius values visually and outputs ready-to-use Bootstrap 5 HTML with the correct inline style applied, no manual CSS writing needed.

Can I create asymmetric or pill-shaped elements with this tool?

Yes. Each corner (top-left, top-right, bottom-right, bottom-left) has its own slider, so you can create pills (set all corners to 50px or more), teardrops (one corner at 0), speech bubbles, and any asymmetric shape. The generated CSS uses the four-value border-radius shorthand, e.g. border-radius: 48px 4px 48px 4px, which works in all modern browsers.

Is it free?

Yes, the CSS Border Radius Generator is completely free with no signup required. Built by the CanvasBuilder.co team.
