What Is Glassmorphism?
Glassmorphism is a UI design trend that creates frosted glass effects using CSS backdrop-filter. Elements appear translucent, blurring the content behind them.
Key properties: semi-transparent background, backdrop-filter: blur(), subtle border, and soft box-shadow. Works in Chrome, Edge, Safari, and Firefox.
Common Use Cases
Tips & Best Practices
Glassmorphism looks best over colorful or image backgrounds. On solid white, the effect is barely visible.
10–30% background opacity gives the best glass feel. Too high and it looks like a solid panel.
Always include -webkit-backdrop-filter alongside backdrop-filter for Safari support.
On unsupported browsers, the semi-transparent background still looks decent without the blur.
Frequently Asked Questions
Does backdrop-filter work in all browsers?
Yes in 2026. Chrome, Edge, Safari, and Firefox all support it. Safari needs the -webkit- prefix.
Is glassmorphism bad for performance?
Backdrop-filter is GPU-accelerated but can be expensive with large blur values on many overlapping elements. Use sparingly on mobile.
Can I animate the blur?
Yes. backdrop-filter is animatable. Transition from blur(0) to blur(12px) for reveal effects.
What is the difference between filter and backdrop-filter?
filter applies effects to the element itself. backdrop-filter applies effects to the area behind the element.
