<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.
