Frequently asked questions
Backdrop blur only has a visible effect when there's something behind the element to blur — a plain solid background won't show off the glass effect, so the live preview uses a colorful gradient to demonstrate it properly.
It's supported in all modern browsers; very old browser versions may not render the blur, though the semi-transparent background alone still provides a reasonable fallback look.
Yes — border opacity is adjustable alongside blur, tint and saturation, since a subtle light border is part of what sells the glass look.
Because the preview renders the real CSS live, you can fine-tune the effect until it looks right before copying a single line of code.
