Why it matters
Glassmorphism and neumorphism look great in a mock-up, but both are known for readability problems. Text on frosted glass changes contrast with whatever scrolls behind it, and neumorphic buttons often have edges too faint for people with low vision to see.
This builder keeps those risks visible: it tests your glass on several backgrounds, warns when contrast drops, and adds a solid fallback for browsers without backdrop-filter. For neumorphism it reminds you to add a visible border or label to anything people need to click.
How to use it
- Choose Glassmorphism or Neumorphism.
- Adjust the tint, blur and border, or the distance and intensity of the shadows.
- Switch the test background to check the card on a busy image.
- Read any warnings, then copy or download the CSS.
FAQ
Does backdrop-filter work everywhere?
In all current browsers. Safari needed the -webkit- prefix until version 18, so the CSS includes both, plus a more opaque background for anything older.
Why does my glass card fail contrast?
Because the background behind it shows through. Raise the opacity or blur, or use darker or lighter text, until it passes on the busiest background it will sit on.
Is neumorphism accessible?
Not on its own: the shadows are subtle by design. Use it for decoration and add a clear border, icon or text for buttons and inputs.
Does blur slow pages down?
Large blurred areas cost graphics power, especially on older phones. Keep glass to cards and bars rather than whole screens.
