<div class="content">
  <p>
    Bulma is a <strong>CSS</strong> framework, meaning that the end result is simply a <strong>single</strong> <code>.css</code> file:
    <br>
    <a href="https://github.com/jgthms/bulma/blob/master/css/bulma.css">https://github.com/jgthms<wbr>/bulma<wbr>/blob<wbr>/master<wbr>/css<wbr>/bulma.css</a></p>
  <p>
    Because Bulma solely comprises CSS classes, the HTML code you write has <strong>no impact</strong> on the styling of your page. That's why <code>.input</code> exists as a class, so you can choose <em>which</em> <code>&lt;input type="text"&gt;</code> elements you want to style.
  </p>
  <p>
    Bulma only styles <strong>generic</strong> tags directly <strong>twice</strong>:
  </p>
  <ul>
    <li>
      <a href="https://github.com/jgthms/bulma/blob/master/sass/base/generic.sass"><code>generic.sass</code></a> to define a basic style for your page
    </li>
    <li>
      the <a href="{{ site.url }}/documentation/elements/content/"><code>.content</code> class </a> to use for <em>any</em> textual content, like WYSIWYG
    </li>
  </ul>
</div>
