title: How to create left and right fixed sidebar with Bootstrap 5
body: <p>In a Bootstrap 5 markup structure, can you use 2 <code>&lt;nav&gt;</code> elements to create a left and right fixed sidebar with content in the middle?  Something like this:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;nav&gt;
    &lt;div&gt;left sidebar&lt;/div&gt;
  &lt;/nav&gt;
  &lt;main&gt;
    &lt;div&gt;main content&lt;/div&gt;
  &lt;/main&gt;
  &lt;nav&gt;
    &lt;div&gt;right sidebar&lt;/div&gt;
  &lt;/nav&gt;
  </code></pre>
  <p>What would the basic bootstrap5 classes look like/css to make this work?</p>
