About css glassmorphism / neumorphism generator
Glassmorphism makes a panel look like frosted glass, with a blurred background behind a translucent surface. Neumorphism makes elements look softly pressed out of the page.
The ingredients of glass
- A semi-transparent background colour such as rgba(255,255,255,0.2).
- backdrop-filter: blur() to soften what is behind.
- A thin light border to define the edge.
Use with care
Both styles can hurt readability and accessibility, particularly neumorphism, where low contrast makes edges hard to see. Test text contrast, give buttons clear boundaries, and add a fallback for browsers without backdrop-filter.
A worked example
A typical glass card uses background: rgba(255, 255, 255, 0.2), backdrop-filter: blur(12px) and border: 1px solid rgba(255, 255, 255, 0.3). It needs a colourful or image background behind it, otherwise the blur has nothing to show.
Performance and support
- backdrop-filter is demanding on low-end phones, so use it sparingly on large areas.
- Provide a solid, semi-opaque background as a fallback for browsers without support.
- Keep text contrast high, since a changing background can reduce readability.
