Space between containers (Desktop View)

I’m working with a slide show and I have two containers inside of a slider, with the slider set to Flex (Horizontal). I have an image in the left container and a heading, paragraph, and a button in the right container. The space that I’m seeing between the two containers on larger desktops seems too wide but I can’t figure out if there’s a way to decrease that gutter/space or if there is a better way to achieve the layout I’m after. Here is a screenshot of what I mean; I’m referring to the space between container 2 and container. The issue is on the Home page of the site.
