title: Is it bad practice to define a "custom" HTML tag
body: <p>I am using a custom HTML tag in my code (<code>&lt;include&gt;</code>). Is this bad practice and if so what should it be replaced with.</p>
  
  <p>It seems to me that it adds readability to the code by having the meaning in the tag name instead of a <code>&lt;div class="include"&gt;</code>.</p>
