Glassmorphism CSS Effect Tutorial - How to Create Glassmorphism

Learn how to create the glassmorphism CSS effect. Dark liquid glass with SVG distortion, neon accents, grid background.

AI agents default to backdrop-filter: blur() and call it glass. Real glassmorphism needs an SVG displacement filter in the DOM, translucent surfaces over visible background content, a 3-sided border trick for the light edge, and dual shadows for depth. Most agents skip all of this.

Copy and paste this glassmorphism CSS code into your AI coding agent (Claude, ChatGPT, Cursor) for instant implementation.

Glassmorphism

AI agents default to backdrop-filter: blur() and call it glass. Real glassmorphism needs an SVG displacement filter in the DOM, translucent surfaces over visible background content, a 3-sided border trick for the light edge, and dual shadows for depth. Most agents skip all of this.

Examples

DISTORTION
Liquid Glass
SVG feTurbulence warps whatever is behind the panel. The colored blobs distort through the translucent surface — plain blur() can't do this.
SPECULAR
3-Sided Border
Top edge bright, left edge medium, base edge dim. Simulates overhead light catching the edge of a glass sheet. One uniform border looks flat.
DEPTH
Dual Shadow
Outer shadow for depth against the background. Inset shadow for the glass thickness and inner darkness. Both are needed for the floating glass slab look.
