Gap between columns

Hi,

I just tested the plugin and i would like to use it on my website, but first there are 2 things that I want to change. Could you please help me with this?

I use the Woo Products Grid for my product archives.

1. I enabled ”Add gap between columns”, but i would like to make the gap bigger, how can i do this? I even want to change the gap on desktop and mobile seperately to make the gap on desktop bigger then on mobile since the screen is a lot smaller.

2. I chose preset 3, but on mobile i would like to hide the add to cart button on the product archive page. Is there a code to do this?

I hope that this is possible!
