This is a template based on my website that has ifames text blocks and account list blocks (areas that you can put in any oreder with any ammount) that you can duplicate and/or add more you can also make a completely new one with this template (yes template for a template):

<div class="w3-bar w3-yellow section">
  <a name="{name}"><h6>{name}</h6></a>
</div>
<div class="w3-bar w3-brown" id="iframes">
  {content}
</div>

You can also change the colors by changing: w3-{color} to: w3-{new color}
