What is CSS backdrop-filter?
CSS backdrop-filter applies visual effects to the content behind an element, not to the element itself. It is commonly used for glassmorphism cards, frosted overlays, sticky headers, and translucent dialogs.
This generator helps you build backdrop-filter values quickly, preview them live, and copy production-ready CSS including the WebKit-prefixed version for better browser support.
How to use this generator
- Adjust blur, brightness, contrast, saturation, and other controls.
- Watch the glass panel update in the live preview.
- Copy the backdrop-filter value or the full CSS rule.
- Paste it into your stylesheet and combine it with a semi-transparent background.
Tips
- Backdrop filters work best with semi-transparent backgrounds such as rgba(255,255,255,0.15).
- Higher blur values create a softer frosted glass effect.
- Saturate and brightness can make the blurred background feel more vivid.
- Add a light border and shadow for a more realistic glassmorphism style.
Backdrop filter checks before applying blur and color effects
Backdrop filters process content behind an element, so stacking, transparency, browser support, and rendering cost determine the real result.
Keep a transparent backdrop
Use a translucent background and verify which layers are actually behind the element; an opaque fill hides the filter result.
Test stacking contexts
Check z-index, transforms, isolation, overflow, fixed elements, and nested filters where compositing can change the sampled backdrop.
Provide a fallback
Choose a solid or translucent fallback that preserves contrast and hierarchy when backdrop-filter is unsupported or disabled.
Profile performance
Measure scroll and animation on mobile hardware and reduce large filtered regions or frequently changing content when frames drop.
