Product category page

Things in woocommerce / Enfold driving me nuts…hope you can help me out

Q1: On my category pages I want to show product list instead of product grid. Where / How do I do that? Possible via quick CSS? Do I need to do CSS “programming” in any php-files (if yes, I am lost anyways…)

Q2: Optionally on my product category pages I want to fit my 5 columns (display 5 products beside each other) within the full content width. Do I need to adapt the product container size or is there another option? The code I found and used (see below) does only change the image size, but not the whole product container. What would be the right CSS code?

#top .thumbnail_container img {
width: 100% !important; }
