Targeting Attribute Pages with ID Tag or something

I’m trying to figure out how to target the pages that are created by product attributes with css. For example, I sell books and I have an attribute “Writer”. I clicked the box for “Enable Archives” so each of my writers can have a page like this: https://alphabetpublishingbooks.com/writer/walton-burns

Now I want to get rid of that blank space where the header should be or do anything with it, preferably via CSS so it doesn’t affect my other headers on other pages. But I can’t seem to find an id or class or anything that targets those pages. My theme developers told me to ask on these forums.

I know you can target individual pages with a page id, but I can’t seem to find the page id or post id for those pages. I tried .archive, but that doesn’t work.

Does any one know?
