How do I resize center column when left and/or right sidebars are disabled?

configuration>layout settings then column right status-global and column left status-global

Set the columns that you are not using to '0'

Explain please. I do not understand what you are talking about. Below is the code I am using to hide the side columns:

if (in_array($current_page_base,explode(",",'wordpress')) ) {
    $flag_disable_right = true;
	 
	
  }

I found a theme that seems to work for wordpress to display from center to right column. So issue is kind of moot now, but I want to get educated on this, so if I need it in the future I know how.

What I want to do is add something after that line that disables the right column, to force center column to resize to occupy space that right column used to have. Or if both right and left columns are disabled then the center column to go to full width.
