  <p>I have this menu page that I want to split into 5 equal columns. </p>
  
  <p>My current CSS for the yellow divs is:</p>
  
  <pre><code>width:20%;
  height:100vh;
  background-color: yellow;
  display:inline-block;
  </code></pre>
  
  <p>Above this, I also have <code>margin:0;</code>. How can I remove the small white gap between the yellow blocks?</p>
