Make a plain HTML page look good and readable with zero effort!

Check out the style guide to see what it looks like.

<!-- CDN Development (always latest) -->
<link rel="stylesheet" href="">
<!-- CDN Production (specific release) -->
<link rel="stylesheet" href="">
# npm package
$ npm install style.css
/* CSS file */
@import url('');


<!doctype html>
<html lang="en">
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Hello World</title>
    <link rel="stylesheet" href="">

The best way to get familiar with the look and feel of style.css is to visit the style guide. Detailed examples of every HTML element (and how to write them in markdown) are available there.


npm install style.css --save-dev

You can use a CSS bundler like sheetify to require style.css like a node module.

const sf = require('sheetify')


Note that any external CSS files imported with sheetify must be compiled using browserify or sheetify-postcss.

Here are some other modules out there for requiring CSS using JavaScript that should also work just fine:


You can also use style.css with Sass.

@import 'path/to/node_modules/style.css/style.scss';

Same goes for the serif variant.

@import 'path/to/node_modules/style.css/serif.scss';

Sass allows you to override defaults more directly. Here are the default settings for style.css:

$font-body:         $system-sans !default;
$font-code:         $system-mono !default;
$font-size-body:    14px !default;
$font-size-scale:   0.25vw !default;
$line-height-body:  1.55 !default;
$line-height-pre:   1.45 !default;
$link-color:        #0074d9 !default;

Using Sass with node_modules

Protip: Sass is easier to use with node_modules when you use the include-path option. Here’s an example of how to use it with node-sass on the command line.

node-sass style.scss -o style.css --include-path node_modules/

This way you can exclude the node_modules/ path prefix in your Sass source code.

Overriding settings

You can override settings like so:

$font-size-body: 14px;

@import 'style.css/style.scss';

If you want to use the font stacks to override global font settings, you can do so like this:

@import 'style.css/src/scss/fonts.scss';

$font-body: $system-serif;

@import 'style.css/style.scss';

The above snippet is how serif.css is generated.


To get started, clone the repository and install dependencies with npm install.



Run npm test to check the generated CSS for errors and issues not caught by the Sass compiler.

We’re using stylelint with a slightly modified version of stylelint-config-standard for now.


Generate style.css from style.scss by running npm run generate.


Publish a new release with npm run release.

The prerelease task will generate CSS, run tests, check if the git index is dirty, and exit if there are any problems. If all goes well, gh-release and npm publish will be run sequentially.


style.css is only possible due to the excellent work of the following collaborators:
