Glassmorphism Generator

How to use Glassmorphism Generator

A glass surface combines a translucent fill with a filtered backdrop. The effect needs varied content behind the element; blur cannot reveal detail on a flat background.

1. Choose the surface color and opacity. Lower opacity shows more of the background and can reduce text contrast.
2. Backdrop blur affects pixels behind the surface, not its own text. Border opacity adds a faint edge, and corner radius sets the shape in pixels.
3. Place the surface above an image, gradient or layered content. Provide a readable solid fallback in your real stylesheet for browsers without backdrop-filter support.

A practical starting point

A translucent caption needs enough fill to remain readable over bright and dark image regions.

background: rgb(255 255 255 / 0.72);
backdrop-filter: blur(16px);
border: 1px solid rgb(255 255 255 / 0.5);

Common mistakes

• Backdrop blur does not blur the element’s children. filter: blur() is a different property.
• Large continuously moving blur surfaces can cost rendering time. Test on a modest mobile device.
