title: Can't use UIkit with Webpack
body: <p>Simply set up a project with webpack. Just install uikit with 
  <code>npm install uikit --save</code></p>
  
  <p>in my main js file I use </p>
  
  <pre><code>import 'jquery';
  import 'uikit/dist/js/uikit.js';
  </code></pre>
  
  <p>In my main html file I write below code </p>
  
  <pre><code>&lt;!doctype html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
      &lt;meta charset="UTF-8"&gt;
      &lt;title&gt;Document&lt;/title&gt;
      &lt;link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/uikit/3.0.0-beta.12/css/uikit.min.css" /&gt;
  &lt;/head&gt;
  &lt;body&gt;
  
  &lt;ul uk-accordion&gt;
      &lt;li class="uk-open"&gt;
          &lt;h3 class="uk-accordion-title"&gt;Item 1&lt;/h3&gt;
          &lt;div class="uk-accordion-content"&gt;
              &lt;p&gt;Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.&lt;/p&gt;
          &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
          &lt;h3 class="uk-accordion-title"&gt;Item 2&lt;/h3&gt;
          &lt;div class="uk-accordion-content"&gt;
              &lt;p&gt;Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor reprehenderit.&lt;/p&gt;
          &lt;/div&gt;
      &lt;/li&gt;
      &lt;li&gt;
          &lt;h3 class="uk-accordion-title"&gt;Item 3&lt;/h3&gt;
          &lt;div class="uk-accordion-content"&gt;
              &lt;p&gt;Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat proident.&lt;/p&gt;
          &lt;/div&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  
  &lt;script src="dist/main.js"&gt;&lt;/script&gt;
  &lt;/body&gt;
  &lt;/html&gt;
