Frequently Asked Questions

Why isn't backdrop-filter blurring what's behind my element?

For backdrop-filter to be visible, the element itself must have a semi-transparent background (e.g., rgba(255, 255, 255, 0.1)) and there must be colorful content or shapes positioned behind it.

Do I still need -webkit-backdrop-filter in CSS?

Including both '-webkit-backdrop-filter' and 'backdrop-filter' ensures full compatibility across older iOS Safari versions alongside modern Chrome, Firefox, and Edge.

Does heavy backdrop-filter blur affect scrolling performance?

Applying large blur radii (>24px) to many overlapping or full-screen elements can increase GPU compositing work on mobile devices. Keep glassmorphism focused on key cards and navigation bars.
