I am having trouble adjusting the size of the image that I want to use for subcategories and collections. I can't seem to find any information online, I am currently using the Debut theme. Would you suggest I switch to a different theme or is it something I can fix with code? Also, I would like to remove `width: 100%` of .site-nav__dropdown site-nav__dropdown--centered site-nav__dropdown--left", but again I am new to your platform and I am not quite sure when I can edit the code for it.
Please share your site url so that I will give you exact solution
