Hero headers and dashboards that call for on-trend frosted panels.
Component libraries where you want consistent blur, radius, and opacity defaults.

Styling tips

Increase blur on complex backgrounds to keep text legible.
Add a subtle border only when the backdrop is bright—dark themes often work better borderless.
Pair the effect with elevated drop shadows for depth without overwhelming the layout.

FAQ

Does the CSS work in all browsers?: Most modern browsers support <code>backdrop-filter</code>. Safari requires the prefixed property, which the snippet includes automatically.
Can I use gradients instead of solid colors?: Yes. Replace the RGBA background in the CSS with your gradient definition while keeping the blur and border values.
How do I make the effect responsive?: Adjust radius and padding in your CSS, or create multiple presets and switch them with media queries.
