Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

HTML Settings

Here you can Sed posuere consectetur est at lobortis. Donec ullamcorper nulla non metus auctor fringilla. Maecenas sed diam eget risus varius blandit sit amet non magna. Donec id elit non mi porta gravida at eget metus. Praesent commodo cursus magna, vel scelerisque nisl consectetur et.

              <p>The first item is blank to allow for the default unmodified component.</p>
<pre id="output"></pre>
              var getPermutations,
  layouts, themes,
  permutations, list;
// The `moduleExports` module comes from 'Settings -> Javascript: Add External Javascript'
getPermutations = moduleExports.getPermutations;

// First item is empty string to allow for 'default' unmodified style
layoutVariants = ['', 'Button--large', 'Button--block', 'Button--emphasis'];
themeVariants = ['', 'th-primary', 'th-secondary', 'th-people', 'th-portal', 'th-social'];

// Get array of arrays of variants
permutations = getPermutations([layoutVariants, themeVariants]);

 Loop through permutations to generate desired output - `variants` is an array of classes
 Could also be used to generate context object for e.g. Fractal
var list = permutations.map(function(variants) {
  return '<li>' + variants.join(' ') + '</li>';
}).reduce(function(memo, item, index) {
  if (index === permutations.length - 1) {
    return memo + item + '</ol>';
  return memo + item;
}, '<ol>');

// Setting innerHTML in this way only for example purposes
document.getElementById('output').innerHTML = list;
🕑 One or more of the npm packages you are using needs to be built. You're the first person to ever need it! We're building it right now and your preview will start updating again when it's ready.
