Formatting checkout button & Sezzle button on cart page

[TripShed1]

I'm looking to format the spacing between the Checkout button and the Sezzle button on my cart page. 

On desktop, it's side by side, and on mobile they're stacked on top of each other. I've been through theme.scss.liquid and sezzle-checkout-button.js but can't seem to find it. 

Thanks!
