Frequently Asked Questions

What is glassmorphism? +

Glassmorphism is a UI design trend that mimics frosted glass — featuring blur, transparency, subtle borders, and shadows to create a layered depth effect. It became popular with iOS and macOS Big Sur designs.

What CSS properties create a glass effect? +

The key property is backdrop-filter: blur() which blurs the content behind the element. Combined with a semi-transparent background (rgba with low alpha), a thin border (rgba white), and box-shadow, you get the glassmorphism look.

Does backdrop-filter work in all browsers? +

backdrop-filter is supported in Chrome, Edge, Safari, and Firefox (since version 103). Add -webkit-backdrop-filter for Safari compatibility. Internet Explorer does not support it.

How do I add a glassmorphism card to my website? +

Copy the generated CSS and apply it to your element. Make sure the element has colorful content behind it — glassmorphism requires visible background content for the blur effect to look good.

What is the best blur value for glassmorphism? +

A blur of 10–16px is typically the sweet spot. Too little (under 5px) and the effect is barely visible. Too much (over 24px) and the background is unrecognizable. Pair with 15–25% opacity for best results.
