Inside the Backdrop Filter Generator
The backdrop-filter property filters the area behind an element rather than the element itself, which is what creates the signature glass look: content shows through, but blurred and tinted. The generator emits a single declaration, and includes the prefixed form for Safari compatibility. Preview updates are pure CSS, so no image processing occurs and nothing leaves your browser.
Limitations worth knowing
backdrop-filter requires a translucent or transparent background on the element, and very heavy blur values can cost performance on low-end devices.
Backdrop Filter Generator FAQ
Why does my element not look blurred?
The element needs transparency; an opaque background hides whatever is behind it and the effect has nothing to show.
Is Safari supported?
Yes, with the -webkit-backdrop-filter prefix, which the generated code includes.
Does blur affect the element's own content?
No, only the backdrop behind it; text and children stay sharp.
