title: Opencart 3.0.2.0 Custum Layout
body: <p>Good afternoon
  Is there anyone who can help me.
  I have been trying for a while, but i do not get it done.
  I use OpenCart 3.0.2.0 and would like a different kind of Layout.
  I would like to select per banner whether it is left, center or right.
  As soon as I choose left or right, this applies to the entire page.</p>
  
  <p>Here is a layout I want:</p>
  
  <p><img src="https://i.stack.imgur.com/w2kCt.png" /></p>
  
  <p>This is what I want. </p>
  
  <p>Can anybody help me with the code? And with file to edit.</p>
