Can I use percentages for border radius values?

Percentage values work well for responsive designs because they scale with the element's dimensions. If you need precise control over the curve, pixel values are more predictable, but percentages adjust automatically when the container size changes.

Do these generators create the CSS code for me?

The generated CSS typically follows the standard border-radius syntax, supporting up to eight values for individual corner control. You can paste the output into any stylesheet without further editing.

Is there a limit to how large the radius values can be?

Both tools allow you to input any numeric value, but practical use usually stays within reasonable ranges. Extremely large values may not produce visible differences depending on the element's size.

Which tool is better for creating pill-shaped buttons?

With 10015 Tools, you can tweak the radius values in the preview window and immediately see if the corners are rounded enough for a pill effect. CodeBeautify is faster if you already know the exact values needed.

Buyer's guide

How to choose a css border radius generator
