Changing size of Variant and Quantity boxes on product pages

Hi there, I'm trying to edit my products so the Add To Cart button shows "above the fold" on each product (ie, you can see it as soon as you land on the page without needing to scroll). I've edited down my descriptions and added clickable details sections below the main section but the thing preventing the Add To Cart from being visible where I'd like it is that the variant and quantity boxes are so unnecessarily large. I'd love to be able to either reduce the size of the boxes or have them side by side. I've linked to a product page that shows what I mean. 

I am not someone who has any knowledge at all about coding and am wondering if there's some idiot-level coding I could do to fix this?

Thanks
