Frequently Asked Questions
How do I create CSS rounded corners online?▾
Use the sliders or number inputs to set each corner radius. Toggle the link button to change all corners at once. The live preview and CSS code update instantly.
What is the difference between px and % for border-radius?▾
Pixel values set a fixed radius. Percentage values are relative to the element size, so 50% creates a perfect circle or pill shape on square or rectangular elements.
Can I set each corner independently?▾
Yes. Click the unlink button to control top-left, top-right, bottom-right, and bottom-left corners independently. Link them again to change all four at once.
What are the common border-radius presets?▾
Common presets include Rounded (8px), Pill (50%), Circle (50%), Leaf (diagonal corners), Tab (top corners only), and Message (chat bubble shape).
Is my data safe when using this border-radius generator?▾
Yes. All CSS generation and preview happens entirely in your browser. No data is ever sent to a server.
