White Blank Space Between Banners

Hi, I'm currently using OpenCart 3.0.2.0 and wondered if there was a way to reduce the space between two banners. I have attached a picture so you can see the issue, the top banner is a slideshow which I have edited the template to remove the dots. I have searched the internet for a solution but keep getting different results. Many thanks

it is probably a margin..
try looking in catalog/view/javascript/jquery/swiper/css/opencart.css
