How to Build Frosted Glass Cards and Soft Neumorphic Elements With Generated CSS
Learn how to tune backdrop blur, transparency and border opacity for glass cards, or distance and blur for neumorphic shadows, then copy the CSS.
Glassmorphism & Neumorphism
Introduction
Glass and neumorphic styles depend on a few numbers working together: blur strength, alpha values and paired light and dark shadows. Getting them wrong produces a muddy card or an element that looks flat. The Glassmorphism & Neumorphism generator renders a sample card on a matching canvas as each slider moves, and the full rule set is copied in one click. Everything runs in the browser.
Step-by-Step Instructions
- Select a mode at the top: Glassmorphism (Frosted Glass) or Neumorphism (Soft UI).
- In glass mode, drag Backdrop Blur (0 to 40px), Background Transparency (0 to 80%) and Border Opacity (0 to 100%) while watching the Frosted Card.
- In neumorphism mode, choose a Shape Style of Flat or Inset to pick between raised and pressed shadows.
- Set Shadow Distance (5 to 50px) and Blur Radius (5 to 80px) until the Soft UI Element has the right depth.
- Press Copy CSS beside Generated CSS Code and paste the rules onto the target element.
Key Use Cases
- Overlay Panels: Produce a translucent navigation bar that blurs the page content scrolling behind it.
- Pricing Cards: Give a feature card a raised neumorphic edge on a light grey section.
- Toggle States: Use the Inset shape for the pressed state of a button and Flat for the resting state.
Frequently Asked Questions
What properties are in the glass output?
The rule includes background as rgba(255, 255, 255, alpha), backdrop-filter and -webkit-backdrop-filter with the blur value, a 1px solid rgba white border using the border opacity, and border-radius: 16px. The alpha values are the slider percentages divided by 100.
Can the neumorphic background or shadow colors be changed?
No. The background is fixed at #e0e5ec with a dark shadow of #a3b1c6 and a light shadow of #ffffff, plus border-radius: 20px. The tool is tuned for a light grey surface, so replace those hex values after copying if the element sits on a different color.
How does the Inset shape differ from Flat?
Flat writes two outer box-shadows, one positive and one negative offset, so the element appears raised. Inset adds the inset keyword to both shadows so the element appears pressed into the surface. Distance and blur apply the same way in both modes.
