title: Spacer is stretched in Outlook?
body: <p>I am using a <code>&lt;div&gt;</code> with <code>line-height: 1px</code> to make a line line like this:</p>
  
  <pre><code>&lt;div style="background-color:#e6e6e6;line-height: 1px"&gt;&amp;nbsp;&lt;/div&gt; 
  </code></pre>
  
  <p>Here it is in gmail:</p>
  
  <p><a href="https://i.stack.imgur.com/frkFH.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/frkFH.png" alt="gmail"></a></p>
  
  <p>But in outlook 2019 on windows it shows like this:</p>
  
  <p><a href="https://i.stack.imgur.com/8rH33.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/8rH33.png" alt="outlook"></a></p>
  
  <p>Does anyone know why this might be happening and if there is a fix? Thanks.</p>
