Glassmorphism means a translucent, blurred panel with a thin light border and a soft shadow. It depends on backdrop-filter, a property that's easy to get visually wrong by hand, since opacity, blur, and border all interact.
Six sliders and a color picker (opacity, blur radius, tint color, border opacity, corner radius, shadow intensity) drive a live preview against three sample backgrounds, and generate the matching CSS block to copy directly into a stylesheet.
When you'd use this
Designing a frosted card, navbar, or modal overlay and wanting to see how the translucency reads before committing values to CSS. The mesh, sunset, and neon preview backgrounds exist because a glass effect looks completely different depending on what sits behind it, and that's near impossible to judge by staring at hex values.
Things to watch for
backdrop-filter only has something to do when there's content behind the panel worth blurring. Placed over a flat, single-color background, a glass panel just looks like a semi-transparent box with no visible blur at all.
The generated CSS includes both backdrop-filter and its -webkit- prefixed form, since Safari and some older Chromium builds only recognize the prefixed version. Browsers with no backdrop-filter support ignore the property outright and render a flat translucent panel without blur, so check your target browser support before shipping this widely.
Frequently asked questions
Does changing the preview background change the CSS I copy?
No. The mesh/sunset/neon buttons only swap what's shown behind the glass panel in the live preview, so you can judge contrast. What you copy is the .glass-panel rule alone (background, backdrop-filter, border, border-radius, box-shadow), never the preview backdrop.
Why does the generated CSS need both backdrop-filter and the -webkit- version?
Safari has historically required the -webkit-backdrop-filter prefix to apply the blur at all, so both properties are included together for the widest browser coverage without you needing to add the prefix manually later.
