Frequently asked questions
Does backdrop-filter work everywhere?
It is supported in modern browsers; add a solid fallback background for older ones.
Why include -webkit-backdrop-filter?
Some browsers still need the prefixed property, so the tool includes it for wider support.
What background works best behind glass?
A colorful or image background makes the frosted effect most visible; flat backgrounds show little blur.
Is the effect expensive to render?
Heavy blur over large areas can cost performance, so use it on focused elements like cards and navbars.
Can I change the border?
The output includes a subtle light border; adjust it in your CSS to match your design.
