  <div class="example">
      In this example, we are using an argument of <code>250px</code> for the <code>fit-content()</code> function. This tells the browser to restrict the first grid column to a width of 350px, causing the text content to break to a new line to fit:

    <div class="example__demo example__demo--fit-content">
      <div class="grid">
        <div class="grid__col-a">
            <p>The simple act of paying attention can take you a long way.</p>
              <p><cite>Keanu Reeves</cite></p>
        <div class="grid__col-b">🏄</div>
      The other value for <code>grid-template-columns</code>, <code>1fr</code>, tells the browser to distribute the remaining space evenly by a factor of one. <a href="https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout/Basic_Concepts_of_Grid_Layout#The_fr_Unit">The <code>fr</code> unit is relatively new</a>, designed to be used with CSS Grid.
