Opencart V2.3x module HTML/CSS fix

On the home page of my Opencart shop, I want to place modules in column left, content top and column right. The problem is when I place certain modules in the content top position (such as Featured or Best Sellers module), they don't automatically fill the full width of the content top position (see attached jpg). Not all modules suffer from this issue as the HTML content module does indeed fill the full width of the content top position. Therefore I want modules such as the Featured or Best Sellers modules to automatically fit the full width of the content top position without an area of white space to the right. I am using the default theme on an Opencart 2.3x website and I specifically want someone with Opencart experience as I may have a few other small tasks that will need performing. Furthermore, if you don't understand the problem after reading this spec and viewing the screenshot then you're not experienced with Opencart 2. Important. Due to the number of idiots that submit bids without actually reading this spec, I am having to repost this project. Therefore to prove you have actually read the spec, please start your bid with the term "Good times ahead". If you don't then I will realize you have not read this spec, are just another spammer and your bid will be instantly rejected. Finally, if you don't understand the problem after reading this spec and viewing the screenshot then you're not experienced with Opencart 2 and no use to me.
