adding space between gallery thumbnails

hey there,
Just wanted to say you guys are amazing and I’ve managed to work around most of my issues by just googling them and reading forum posts.

However, I did try finding a solution to my current issue by looking through other posts but none seemed to work for me. All I want to do is add space between my gallery thumbnails (upcoming events) so they are not touching each other. I am assuming there must be some quick css I can add to the general styling area.

For the gallery I set up 2 – one for view on larger screens and one for smaller screens. I want the padding on the one I have set for larger screens only… do I have to set a class id for that particular gallery?…. i.e. is any css code you give me going to change all galleries if I don’t?

Oh and one small other thing… I’d like to set my footer widget columns to align bottom, instead of top.

Any help would be greatly appreciated. – Danielle
