Common Uses for Border Radius
Buttons & CTAs
Create rounded buttons and call-to-action elements with consistent border radius.
Image Styling
Round image corners or create circular avatar images with border-radius.
Card Components
Design card layouts with smooth rounded corners for modern UI patterns.
Container Design
Style modal dialogs, tooltips, and overlay containers with rounded edges.
How It Works
Choose a Preset or Customize
Start with a quick preset like Small, Medium, Circle, or customize each corner individually using the sliders and inputs.
Select Your Unit
Choose between pixels (px), em, rem, or percentage (%) units. Percentages create responsive rounded corners that scale with the element.
Copy the CSS
Once satisfied with your border radius, copy the generated CSS code and paste it into your stylesheet.
Border Radius Tips
Use 50% for Circles
Set border-radius to 50% on a square element to create a perfect circle. This works regardless of the element's size.
Pill-Shaped Buttons
Use a very large pixel value (like 9999px) to create pill-shaped buttons that work at any width.
Percentage Behavior
When using percentages on non-square elements, each corner becomes elliptical. This can create unexpected shapes on rectangles.
