Visually generate frosted-glass CSS effects for your UI.
Adjust five sliders — blur, transparency, border opacity, border radius, and border width — and watch the frosted-glass effect update in real time against a colorful preview background. When you're happy with the look, copy the ready-to-use CSS and paste it straight into your stylesheet.
Use the five sliders to adjust Blur Amount, Transparency, Border Opacity, Border Radius, and Border Width. The preview box updates live. Copy the generated CSS from the text box at the bottom of the controls panel.
Glass-style UI works best when it feels deliberate rather than ornamental. A panel needs enough blur to separate itself from the background, enough opacity to support readable content, and enough edge definition to keep its shape. Those decisions are visual, subtle, and hard to make from raw CSS values alone.
This tool lets you tune that surface directly and carry the resulting CSS into a real interface.
Glass panels are often used to lift text or controls off an image or colorful backdrop without fully blocking it.
Menus, side panels, and floating cards sometimes benefit from feeling lighter than a solid block of color.
If a product language uses translucent layers, you often need a repeatable way to compare subtle variants rather than reinventing the effect component by component.
A strong blur can look polished in a demo and still feel heavy or distracting once repeated across a real interface.
If the background shows through too aggressively, the effect stops helping readability and starts undermining it.
In glass-style UI, the edge treatment often does more work than people realize. Without enough definition, the panel loses its shape.
This is where the effect can be genuinely useful: soft separation without a fully opaque block.
Some layouts benefit from a lighter surface treatment, but only if the panel still reads clearly over real content.
If the effect is part of a broader UI language, consistency matters more than any one dramatic example.
This tool generates the visual CSS for a glass effect. It does not guarantee text contrast, solve performance tradeoffs on weaker devices, or decide whether the effect is a good design choice in the first place. It helps you tune the treatment, not justify it.
Done well, glass effects create separation without visual heaviness. Done badly, they reduce legibility. A generator is useful because the line between those two outcomes is usually a matter of small settings, not big ideas.
Glassmorphism requires a colorful or image-based background behind the element. On a plain white background, the blur has nothing to act on and the effect isn't visible.
