Frequently asked questions

What is glassmorphism in web design?

Glassmorphism is a style that mimics frosted glass: a semi-transparent surface with a background blur, a subtle border and a soft shadow. It creates a sense of depth and layering, popularized by macOS and Windows interfaces.

How does backdrop-filter create the glass effect?

backdrop-filter applies graphical effects like blur() to the area behind an element rather than the element itself. Combined with a semi-transparent background color, the blurred content behind the card produces the frosted look.

Does backdrop-filter work in all browsers?

It works in all modern browsers, though Safari needs the -webkit-backdrop-filter prefix, which this tool includes automatically. Very old browsers ignore it and simply show the semi-transparent background instead.

Why is my glassmorphism effect not blurring?

backdrop-filter only blurs content that is actually behind the element, so there must be something (an image or gradient) behind it, and the element's background must be semi-transparent. A fully opaque background hides the blur.

Is glassmorphism accessible?

It can reduce text contrast, so keep the background tint opaque enough and test contrast against the busiest part of the backdrop. Add a solid fallback color for browsers that do not support backdrop-filter.
