    Bulma is highly customizable thanks to <strong>415 Sass variables</strong> living across <strong>28 files</strong>.
  </p>

  <p>
    These variables exist at 3 levels:
  </p>

  <ul>
    <li>
      <strong><a href="/documentation/overview/variables/#initial-variables">initial variables</a></strong>: global variables with <strong>literal</strong> values
    </li>
    <li>
      <strong><a href="/documentation/overview/variables/#derived-variables">derived variables</a></strong>: global variables with values that reference other variables, or are computed
    </li>
    <li>
      <strong>element/component variables</strong>: variables that are specific to a Bulma element/component
    </li>
  </ul>
