title: Using negative integers with implicit rows in CSS Grid
body: <p>I am trying to make a simple sidebar layout with a flat HTML structure, in which the first <code>&lt;aside&gt;</code> element fills in the 1st column completely.</p>
  
  <p>My problem is, that the negative row end value seems to not work for the implicitly created rows for all my elements in the 2nd column.</p>
  
  <p>Expected:</p>
  
  <p><a href="https://i.stack.imgur.com/jyjHp.png" rel="noreferrer"><img src="https://i.stack.imgur.com/jyjHp.png" alt="enter image description here"></a></p>
  
  <p>Actual:</p>
  
  <p><a href="https://i.stack.imgur.com/CNFRf.png" rel="noreferrer"><img src="https://i.stack.imgur.com/CNFRf.png" alt="enter image description here"></a></p>
  
  <p>Below is a runnable code snippet that illustrates the problem.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>article {
    display: grid;
    grid-template-columns: 200px 1fr;
    background: gray;
  }
  
  aside {
    grid-row: 1/-1;
    grid-column: 1/2;
    background: pink;
  }
  
  section {
    grid-column: 2/3;
    background: yellow;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;article&gt;
    &lt;aside&gt;In the left column (top to bottom)&lt;/aside&gt;
    &lt;section&gt;In the right column&lt;/section&gt;
    &lt;section&gt;In the right column&lt;/section&gt;
    &lt;section&gt;In the right column&lt;/section&gt;
  &lt;/article&gt;</code></pre>
  </div>
  </div>
