Problems with Tradmart theme

I have a theme purchased on elements installed on shopify, it is having a problem and I need help, eg. this spacing on the sides is appearing in all browsers, could someone help me please

As the items from Elements don’t come with the item support, the only solution would be a theme customization, if you’re interested in paid support, I’d be happy to help on this.
( I’m aware of the problem is not too complicated but it’s time consuming job )

how much does it cost?

Please, drop me an email to discuss the details.
