title: Setting grid items to not Overlap when sharing the same row and column
body: <p>Right now, when two grid items share the same row and column they overlap each over.</p>
  
  <pre><code>&lt;div class="some-grid-container"&gt;
      &lt;div style="grid-row: 1; grid-column: 1"&gt;Item 1&lt;/div&gt;
      &lt;div style="grid-row: 1; grid-column: 1"&gt;Item 2&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>How do I them not overlap? Probably behave like flex items when sharing the same row and column. (Without making an outer container).</p>
