Cannot find the CSS styles

Hello,

first of all I would like to thank you for this wonderful theme. It does exactly what we need, right out of the box! What a time saver and what a professional look!

I have two CSS questions though that I couldn't solve myself. Obviously it is just my lack of knowledge and I am sure you can help me here.

1. As you can see by the attached images, the 'old' version is the node full-view display of a list as it is right 'out-of-the-box' and I cannot find the style how to change it to the 'new' version. Can you help me with this?

2. To have the same 'look and feel' on all modules I will have to change the css files of some modules. Can I simply copy and paste their css styles into the custom-style.css and change it there? What do I have to do to make the modules ignore their standard css files, so with new updates coming up I won't have to do it over and over again?

I hope I explained it properly and that you will be able to help me. Thank you for taking your time.
