Key features

The iTwinUI package is a CSS (Sass/SCSS) library for building beautiful and well working web UI components with support for multiple color themes within Bentley Systems & iTwin.js applications.

The goal of this project is to transform UX design specifications into flexible and usable style for Bentley web applications. This is accomplished by developing the style using Sass (.scss) and providing end users with that Sass, as well as CSS. This provides great flexibility to the end user and more readily enables adoption of the iTwinUI standards.


Install

npm install @itwin/itwinui-css
yarn add @itwin/itwinui-css

Use

You need to add iui-body class to your <body> element in order to get recommended stylings.

Using Sass:

@import '@itwin/itwinui-css/scss/variables';

.my-class {
  padding: $iui-m;

  @include themed {
    color: t(iui-text-color);
  }
}

Note: We highly recommend using post-processing tools for CSS (like postcss and autoprefixer) to add vendors' prefixes as we are not doing that manually in SCSS.

Using CSS (applying global styles):

@import '@itwin/itwinui-css/css/global';
