Add-On Product Custom Spacing

@tuanphan 

Is anyone able to help me figure out how to adjust the spacing in the Add-On Product Section? The "Select a Size" width seems too large, and "Add to Estimate" width is obviously too small. I've tried playing with padding but have had no luck. It looks great on mobile, but desktop needs some work!

Thanks!

Can you share link to this product?

Thanks @tuanphan  -- in case anyone else follows up on this in the future. Your code worked great, but it altered the spacing for regular products AND add-on products. I adjusted it slightly to target just the add on product, without impacting the regular product.
