clay.css - CSS util for creating inflated fluffy 3D claymorphic shapes | Product Hunt


Claymorphism is a fresh new concept. The name was coined by Michał Malewicz and the designers are excited to explore the possibilities of this approach to UI design.

It features inflated fluffy 3D elements which look charming and introduce a much more vibrant look compared to the usual flat designs.

What sets claymorphism apart from neumorphism is that it floats above the background instead of being connected to it, eliminating accessibility issues and design restrictions of the latter.





npm i claymorphism-css
yarn add claymorphism-css


Download and add the dist/clay.css or dist/clay.scss manually.


This is a minimal, single class CSS util that applies only basic claymorphism styles:

  • Background
  • Border radius
  • One outset shadow
  • Two inset shadows
<div class="clay">
  Fluffy ipsum dolor sit amet consectetur...

This CSS class allows you to easily change the claymorphic styles via CSS properies. These changes and additional styles should be applied with the extending class.

<div class="clay card">
  Fluffy ipsum dolor sit amet consectetur...
  /* Modify clay.css properties */
  --clay-background: #f76d6d;
  --clay-border-radius: 48px;

  /* Extended styles */
  color: #f1f1f1;
  padding: 48px;

Options (CSS Variables)


SASS Mixin

SASS mixin allows you more flexibility in applying claymorphism styles to your components. For example, this way you can easily add styles to pseudo-elements or pseudo-selectors or use the mixin in other SASS mixins or functions.

@import "claymorphism-css/dist/clay.scss";

@import @include clay(
  $background: [value],
  $border-radius: [value],
  $shadow-outset: [value],
  $shadow-inset-primary: [value],
  $shadow-inset-secondary: [value]
