// quick guide

Glassmorphism is a popular UI design trend characterized by a translucent, frosted-glass look. It uses a combination of background opacity, subtle borders, shadows, and the CSS backdrop-filter property to blur elements behind the panel.

How to use this tool:

Adjust the sliders to control the Blur amount, background Opacity, and color Saturation.
Fine-tune the border radius, border thickness, and shadow intensity.
Watch the changes update in real time over the sample background.
Copy the generated CSS code block, which includes Webkit vendor prefixes for Safari support.

// frequently asked questions

What is backdrop-filter in CSS?

The <code>backdrop-filter</code> CSS property applies graphical effects—such as blurring or color shifting—to the area behind an element. Unlike standard <code>filter</code>, which affects the element itself, backdrop-filter blurs whatever is behind it.

Is glassmorphism supported in Safari?

Yes. Safari requires the vendor prefix <code>-webkit-backdrop-filter</code> to render the blur effect. The code generated by this tool includes this prefix automatically.

Can glassmorphism cause web performance issues?

Yes, heavy use of backdrop-filter blur effects can be resource-intensive for the browser to render, especially on mobile devices or slow GPUs. We recommend using it selectively on headers, cards, or modals.
