}What is a Glassmorphism Generator?
Glassmorphism is a modern UI design trend that creates a frosted glass effect using CSS backdrop-filter: blur() combined with semi-transparent backgrounds. The effect gives elements a translucent, glass-like appearance that lets the background show through with a beautiful blur, creating depth and visual hierarchy in user interfaces.
CodeHelper's Glassmorphism Generator lets you customize every aspect of the glass effect: blur intensity, opacity, border radius, border width, shadow, and color. See the result in real-time on multiple gradient backgrounds and copy the production-ready CSS.

Frequently Asked Questions
Why does the blur slider not change anything on my page?
backdrop-filter blurs what is behind the element, so it needs content, images, or shapes underneath the glass. On a flat single-color background there is nothing to blur. That is why the preview here places shapes behind the card. Also make sure the glass element has a semi-transparent background, since a fully opaque one hides the blur.
Does backdrop-filter work in Safari and Firefox?
Yes. Safari needs the -webkit-backdrop-filter prefix, which the generated CSS includes. Firefox has supported the unprefixed property since version 103 and Chrome and Edge since version 76. For older browsers you can add a fallback with a more opaque background inside an @supports not (backdrop-filter: blur(1px)) block.
What blur and opacity values look best for glassmorphism?
A blur between 8px and 20px with a background alpha between 0.15 and 0.35 is the usual sweet spot. Add a 1px border in the same color at a slightly higher alpha to give the edge a highlight, and keep the shadow soft. Very high blur values are expensive to paint, so avoid stacking many blurred cards on one screen.
Can I use the generated CSS in Tailwind?
Yes. The equivalent utilities are backdrop-blur-md or an arbitrary backdrop-blur-[16px], bg-white/25 for the translucent background, border border-white/40, rounded-2xl and shadow-lg. Or paste the generated block into your CSS file as a .glass class and apply it next to your Tailwind classes.
