How to build a glassmorphism panel

  1. 01

    Choose the glass tint

    Pick a Glass tint color. The preview floats the panel over two colored orbs, so the material is judged against a busy background the way it will be on a real screen.

  2. 02

    Set opacity and blur

    Surface opacity runs from 0.05 to 0.8 — lower means more transparent — and Backdrop blur from 0 to 40 px softens whatever sits behind the panel.

  3. 03

    Tune saturation, border, and radius

    Saturation (50–200%) enriches or mutes the backdrop, Border opacity (0–0.8) traces the edge in the tint color, and Corner radius (0–48 px) rounds the panel.

  4. 04

    Balance the material

    The surface controls trade off against each other: low opacity needs more blur to read as glass, and Saturation above 100% keeps a busy backdrop from washing out behind a pale tint. The default material — white tint at 0.22 opacity, 18 px blur, 140% saturation — is a proven middle.

  5. 05

    Copy the panel CSS

    Press Copy CSS or Download .css to save toolars-glass-panel.css. The .glass-panel rule combines an rgba background, backdrop-filter with its -webkit- twin, a 1 px tint border, and a soft shadow.

  6. 06

    Plan the fallback

    If backdrop-filter is unavailable, the rgba background, border, and shadow still render. Setting Backdrop blur to zero is only a rough visual check because the saturation filter may still apply. Test the CSS in target browsers and raise Surface opacity if text needs more contrast.

What CSS Glassmorphism Generator actually does

A music player's floating control bar, a notification card hovering over a map, a login panel suspended above a photo wall — frosted glass sells depth without hiding the page. The effect depends entirely on what sits behind it, which is why this preview renders colored shapes for the blur to work on, and the whole exploration happens locally, so an unreleased interface's palette never leaves the device. Once the material balances, the exported rule carries every decision with it.

Common questions

Which CSS does the export produce?
One .glass-panel rule: an rgba background from your tint and opacity, backdrop-filter: blur() saturate() in both standard and -webkit- forms, a 1 px border in the tint at your border opacity, your corner radius, and a fixed soft drop shadow.
Does glassmorphism work in every browser?
Backdrop-filter support and rendering vary by browser and version. The export includes standard and -webkit- declarations but no runtime detection. Without the filter, the translucent background, border, and shadow remain; check text contrast against the real background.
Why does the preview need those colored orbs?
backdrop-filter processes whatever sits behind the element, so glass over a blank background shows nothing. The orbs give the blur and saturation something real to work on — the same reason glass effects need busy backdrops in production.
What is fixed in the exported rule?
Three things: the border width is always 1 px, the border color is always your tint at your chosen Border opacity, and the drop shadow is a fixed soft spread. Everything else — background, blur, saturation, radius — tracks your controls directly.
How opaque should the glass be?
Stay in the lower half of the range for panels floating over content — the 0.22 default keeps backgrounds legible through the material. Push higher only when the panel carries text that must survive a busy backdrop, and check contrast at your real font sizes.
Are my settings uploaded?
No. The panel is computed and previewed entirely in this tab with no account, and nothing is stored, logged, or sent. Press Reset to restore the default material.
