Glassmorphism Generator Online: Frosted Glass CSS in Five Sliders

Glassmorphism — the frosted, translucent panel look popularized in modern UI design — comes from a small set of CSS properties working together: a semi-transparent background, a blur applied to whatever sits behind it, a subtle light border, and a soft shadow. Getting the combination right by hand means a lot of trial and error with rgba values; a generator turns it into five sliders.

The Five Controls

• Blur — how much the background behind the panel gets blurred (0-40px)
• Tint color and opacity — the panel's own semi-transparent color wash (0-100%)
• Border radius — how rounded the panel's corners are (0-48px)
• Border opacity — a subtle light border that helps the glass edge read clearly
• Shadow — a soft drop shadow that lifts the panel off the background

The Generated CSS

At default settings (12px blur, 20% white tint, 16px radius, 30% border opacity, 37% shadow):

background: rgba(255, 255, 255, 0.2);
backdrop-filter: blur(12px);
-webkit-backdrop-filter: blur(12px);
border-radius: 16px;
border: 1px solid rgba(255, 255, 255, 0.3);
box-shadow: 0 8px 32px 0 rgba(31, 38, 135, 0.37);

Six lines, ready to paste directly onto any element that needs the effect — no manual rgba math required.
