Frequently Asked Questions

What is Glassmorphism in UI design?

Glassmorphism is a design style that creates frosted glass-like UI elements. It uses CSS backdrop-filter: blur() combined with semi-transparent backgrounds to create elements that blur and tint the content behind them. The effect mimics real frosted glass and is popular in modern UI design.

How do I create a glassmorphism effect in CSS?

To create glassmorphism in CSS, combine: background: rgba(255,255,255,0.25) for transparency, backdrop-filter: blur(10px) for the frosted effect, a subtle border like border: 1px solid rgba(255,255,255,0.2), and border-radius for rounded corners. Include -webkit-backdrop-filter for Safari.

Does backdrop-filter work in all browsers?

backdrop-filter is supported in all modern browsers including Chrome, Edge, Firefox, and Safari. For Safari, use the -webkit-backdrop-filter prefix. The effect has good support since 2020. For older browsers, consider providing a solid fallback background color.

What backgrounds work best with glassmorphism?

Glassmorphism looks best over colorful, varied backgrounds where the blur effect is visible. Gradients, images, and multi-colored content behind the glass element showcase the effect well. Solid color backgrounds will still work but the blur effect will be less noticeable.

How do I make glassmorphism more visible?

To make glassmorphism more visible: increase the blur value (15-20px), add a subtle border with rgba(255,255,255,0.3), increase the background opacity slightly, boost saturation above 100%, and ensure there is colorful content behind the element to blur.

Can I use glassmorphism with dark mode?

Yes, glassmorphism works great with dark mode. Use dark or tinted semi-transparent backgrounds like rgba(0,0,0,0.25) or rgba(30,30,30,0.4). The blur effect still works beautifully, creating an elegant smoky glass appearance. Our generator lets you pick any glass color.
