💡 UI Design Tips for Smooth Rounded Corners

  • Consistent Scale: Maintain fixed corner radii across components (e.g., 8px for small inputs, 16px for cards) for brand cohesion.

  • Asymmetric Organic Shapes: Set opposing corners (like Top-Left 40px and Bottom-Right 40px) to create modern leaf or blob shapes.

  • Pill Buttons: Increase corner radius values equal to or greater than the component height to generate rounded capsule buttons.

  • ❓ Frequently Asked Questions (FAQ)

    What is the CSS shorthand for border-radius?

    The standard shorthand follows clock-wise ordering: border-radius: [top-left] [top-right] [bottom-right] [bottom-left];.

    Can I use percentage values instead of pixels?

    Yes! Setting border-radius: 50%; creates perfect circles on square containers, while pixel values provide fixed-size corner rounding.
