Quick Answer
How do you create glassmorphism in CSS?
// Answer
Glassmorphism combines a semi-transparent background with a backdrop-filter: blur(), a subtle border, and a soft shadow. The blur frosts whatever is behind the element, while the transparency lets color bleed through — creating a pane-of-glass look.
Why use this tool
Modern frosted UI
Glassmorphism is everywhere in modern interfaces — cards, navbars, and overlays. Tuning the blur and transparency by hand is fiddly; this tool previews the effect over a colorful background and gives you copy-ready CSS, including the -webkit- prefix for Safari.
