Removing White Gap Between Product Images Homepage Boundless Theme Mobile View

In the Boundless theme mobile view the gap between the images is too wide. I would like to close the gap a bit but can’t figure out the proper code.

This is what the mobile view looks like with the gaps.

This is what I would want the images to look like. Similar to what the images would look using the minimal theme.

I like the boundless theme full screen slide show and like the way the minimal theme has the products images on mobile view. Using the boundless theme if I choose the option to make the image larger it switches the products from side by side to a single image. Please Help. Thanks in advance.
