Why this matters

Design decisions that stay in a design tool cost engineering time to translate. Generating real CSS — with real contrast ratios and real token names — closes that gap and keeps your interface consistent as it grows.

Popular Use Cases

  • Case 1
    Generate accessible color palettes and gradients for landing pages.
  • Case 2
    Copy production-ready CSS for shadows, radii and text effects.
  • Case 3
    Prototype hover, focus and dark-mode variants without a design tool.
  • Case 4
    Standardise design tokens across a component library.

Industry Best Practices

  • Read the field labels, units, and instructions before using Border Radius Generator.
  • Keep a copy of important source material when the operation could change or transform it.
  • Review the result before sharing or relying on it; check the page for available copy or download controls.
  • Cross-check consequential results against an authoritative source; this tool does not replace professional advice.
  • Review Border Radius Generator's data-handling notice before entering sensitive information.

Key Terms Explained

Contrast ratio
The luminance relationship between text and background. WCAG AA requires 4.5:1 for body text.
HSL
Hue, Saturation, Lightness — a colour model that makes generating tints and shades far easier than hex.
Design token
A named value (colour, radius, spacing) shared between design and code so both stay in sync.
Elevation
The perceived height of a surface, usually expressed through layered box-shadows.

Frequently Asked Questions

Is the CSS from Border Radius Generator production-ready?›

Yes — output is plain, standards-compliant CSS with no vendor lock-in, ready for a stylesheet, a Tailwind config or a design-tokens JSON file.

Is Border Radius Generator free to use?›

Yes — Border Radius Generator is completely free with no signup, watermark, trial or hidden paywall, however often you use it.

Does Border Radius Generator check colour contrast?›

Preview your values on both light and dark surfaces before shipping; aim for WCAG AA (4.5:1 for body text, 3:1 for large text).

Does Border Radius Generator work on mobile phones and tablets?›

Yes. The layout is mobile-first and tested on iOS Safari, Android Chrome and every current desktop browser, with tap targets sized for thumbs.

Can I save my values as design tokens?›

Copy the output as CSS custom properties and paste it into your token file — the naming stays consistent so a design system can consume it directly.

Is my data safe when I use this border radius?›

Data handling varies by tool. Read the notice above the workspace to see whether your input stays in the browser or is sent to a named provider or service. Avoid entering sensitive information unless you understand that tool's handling.

Will this border radius look identical in every browser?›

Modern Chrome, Safari, Firefox and Edge render these properties identically. Very old browsers may ignore newer colour spaces and fall back to the nearest sRGB value.
