<div class="content">
  <p>Bulma has <strong>two</strong> variable files divided into <strong>4</strong> sections:</p>

  <ol>
    <li>
      <strong>Initial variables</strong>: where you define variables by <strong>literal value</strong>, like:
      <ul>
        <li><strong>colors</strong>: <code>{{ initial_vars['$blue'].name }}: {{ initial_vars['$blue'].value }}</code></li>
        <li><strong>font sizes</strong>: <code>{{ initial_vars['$size-1'].name }}: {{ initial_vars['$size-1'].value }}</code></li>
        <li><strong>dimensions</strong>: <code>{{ initial_vars['$gap'].name }}: {{ initial_vars['$gap'].value }}</code></li>
        <li><strong>other values</strong>: <code>{{ initial_vars['$easing'].name }}: {{ initial_vars['$easing'].value }}</code> or <code>{{ initial_vars['$radius-large'].name }}: {{ initial_vars['$radius-large'].value }}</code></li>
      </ul>
    </li>
    <li>
      <strong>Derived variables</strong> where variables are <strong>calculated</strong> from the values set in the previous file. For example, you can have:
      <ul>
        <li>
          <strong>Primary colors</strong> derived from the initial variables:
          <ul>
            <li><code>{{ derived_vars['$primary'].name }}: {{ derived_vars['$primary'].value }}</code></li>
            <li><code>{{ derived_vars['$link'].name }}: {{ derived_vars['$link'].value }}</code></li>
            <li><code>{{ derived_vars['$info'].name }}: {{ derived_vars['$info'].value }}</code></li>
            <li><code>{{ derived_vars['$success'].name }}: {{ derived_vars['$success'].value }}</code></li>
            <li><code>{{ derived_vars['$warning'].name }}: {{ derived_vars['$warning'].value }}</code></li>
            <li><code>{{ derived_vars['$danger'].name }}: {{ derived_vars['$danger'].value }}</code></li>
            <li><code>{{ derived_vars['$dark'].name }}: {{ derived_vars['$dark'].value }}</code></li>
            <li><code>{{ derived_vars['$text'].name }}: {{ derived_vars['$text'].value }}</code></li>
          </ul>
        </li>
        <li><code>{{ derived_vars['$background'].name }}: {{ derived_vars['$background'].value }}</code>: a general background color</li>
        <li><code>{{ derived_vars['$link'].name }}: {{ derived_vars['$link'].value }}</code>: the links use the primary color</li>
        <li><code>{{ derived_vars['$family-primary'].name }}: {{ derived_vars['$family-primary'].value }}</code>: the primary font family is the sans-serif one</li>
        <li>
          <strong>Lists and maps</strong> which are collections of already defined variables:
          <ul>
            <li><code>{{ derived_vars['$colors'].name }}: {{ derived_vars['$colors'].value }}</code></li>
            <li><code>{{ derived_vars['$shades'].name }}: {{ derived_vars['$shades'].value }}</code></li>
            <li><code>{{ derived_vars['$sizes'].name }}: {{ derived_vars['$sizes'].value }}</code></li>
          </ul>
        </li>
      </ul>
    </li>
  </ol>

  <p>
    To <strong>override</strong> any of these variables, just set them <em>before</em> importing Bulma.
