Hello Victor, Maybe I did not explain properly, Yes i know you can build banner sizes as you suggest, but if we use those sizes in the simple template layout they do not fit properly, there is a 250 pixel left or right, then if we try and use the 768 banner in the other section it distorts the layout as it is designed different and is only about 690 wide, so this makes it hard to apply and use standard banner sizes within the standard layout. ? unless I am doing something wrong, so I was suggesting to try the standard banner sizes in your demo to ensure the layout is not distorted when used.
