How can I change the size of the pictures in this example http://codepen.io/anon/pen/IDKAo I am making a photo gallery with this effect, and I need to change the size of the pictures, can anyone help? It is a pretty complex css so I understand if you can't.
@LastMitch, First of all this account is not just mine its mine and two of my friends that are in a class together, and yes I do try, in this instance, I can't change the size of the images because in the CSS it is under background-image. And the background-size tag doesn't work. @Michael, There are no img tags, I am not that clueless :)
