Backdrop filtering needs transparency

The effect applies to pixels behind the element, so a fully opaque foreground background hides it. Modern browsers support backdrop-filter, but older clients can still need a plain translucent fallback.

Performance matters

Large animated blur regions can be expensive. Test scrolling and animation on the real page rather than assuming a static preview predicts runtime cost.
