CSS Glassmorphism Generator

What is this tool?

A visual generator for the "glassmorphism" design style (translucent, blurred-background cards). Adjust blur, transparency, tint color, border and shadow with sliders, watch the card update live, and grab the CSS or Tailwind output.

When to use it

  • Designing a frosted-glass card, modal or navbar for a website
  • Prototyping a glassmorphic UI element before building it
  • Generating ready-to-paste CSS for a design system
  • Exploring how blur and transparency values look together before committing to values
  • Getting the equivalent Tailwind classes for an existing design

How to use it

  1. 1Adjust the blur, transparency and tint controls to shape the glass effect
  2. 2Set the border color/width and shadow intensity
  3. 3Preview the card against the background swatches provided
  4. 4Switch the output tab to CSS or Tailwind
  5. 5Copy the generated code into your project

Frequently asked questions

Will this work in every browser?

Backdrop blur (backdrop-filter) is supported in all current major browsers; very old browsers may not render the blur.

Can I use the Tailwind output directly?

Yes — it's a set of standard utility classes you can paste straight into a className, no config changes needed for the basics.

Does changing the background preview affect the generated CSS?

No — the background swatches are only there to preview how the glass effect looks against different content; they're not part of the copied output.

Can I get a solid (non-glass) fallback?

Not automatically — you can drop backdrop-filter from the copied CSS if you want a plain translucent card without blur.
