@siimple/css is a light, responsive and open source CSS toolkit for design flat and clean websites. It has been built in SASS/SCSS and provides a clean starting point for your web design.


Please read our migration guide to migrate from older versions to v4.


The @siimple/css package is available on npm, so you can run the following command to add it to your project:

$ npm install --save @siimple/css

This package is also available on a CDN, so you can import the compiled CSS files directly on your HTML page.


You can include the compiled styles in your HTML files:

<link rel="stylesheet" href="./node_modules/@siimple/css/dist/siimple.min.css">

The source files are written in Sass, so you can import all the styles in your scss files:

@import "@siimple/css/index.scss";

Or import individual modules:

@import "@siimple/css/scss/elements/btn.scss";
@import "@siimple/css/scss/components/alert.scss";

Make sure that you have added your node_modules folder to your Sass include paths.


The documentation website is available at docs.siimple.xyz.
