title: What's the difference between grid-column value 1/1 and 1/2?
body: <p>In CSS grid, <code>grid-column: 1/1</code> and <code>1/2</code> are showing the same result. Is there any difference between them? Look at the code below.</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>.grid-container {
    display: grid;
    grid-template-columns: auto auto auto auto;
    grid-gap: 10px;
    background-color: #2196F3;
  }
  
  .item1 {
    grid-column: 1 / 2;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div class="grid-container"&gt;
    &lt;div class="item1"&gt;1&lt;/div&gt;
    &lt;div class="item2"&gt;2&lt;/div&gt;
    &lt;div class="item3"&gt;3&lt;/div&gt;
    &lt;div class="item4"&gt;4&lt;/div&gt;
    &lt;div class="item5"&gt;5&lt;/div&gt;
    &lt;div class="item6"&gt;6&lt;/div&gt;
    &lt;div class="item7"&gt;7&lt;/div&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
  
  <p><code>grid-column</code> value <code>1 / 2</code> and  <code>1 / 1</code> is same. What's the difference?</p>
