What is Glassmorphism?

Glassmorphism is a modern UI design trend that creates frosted glass effects using CSS backdrop-filter and semi-transparent backgrounds. It became popular in 2020 with Apple's macOS Big Sur and has since been adopted by designers worldwide for creating elegant, layered interfaces.

The key properties are backdrop-filter: blur() for the frosted effect, a semi-transparent background color, and a subtle border to define the glass edge.

Browser Support

backdrop-filter is supported in all modern browsers including Chrome, Firefox, Safari, and Edge. Use the -webkit- prefix for maximum compatibility.

Performance Tips

Blur effects can impact rendering performance. Use will-change: backdrop-filter and avoid applying glassmorphism to many overlapping elements simultaneously.

Design Best Practices

Place glass elements over colorful or image backgrounds for the best visual effect. The frosted blur needs underlying content to look compelling.

Accessibility Notes

Ensure sufficient contrast between text and the glass background. Test with various underlying content to verify readability in all scenarios.
