Thank you. From what I can figure out going through the source of my pages, I only use:
1. Front page (Magazine Template): magazine-unit-img-wrap-inn (1024px wide?)
2. Blog page (Blog list Template): blog-unit-img (1024px wide?)
3. Post (Portfolio Template): list-layout-img gallery-images-img (800px wide?)
4. Post (Standard Template): I insert photos in the content and I control the width, usually full size
I don’t use page builder.
Based on this, can I safely delete the lines you stated?
