Check for second or third page?

I’ve currently got a blog set up using Hugo that lists the first 10 posts, and then provides a button to “Older Articles” for content beyond that. However, I’d like to have a slightly different design (just some minor CSS tweaks) for any additional pages past the initial 10 posts (i.e. page 2, page 3, and so on).

How would I go about detecting whether I’m not on the home page?

If that’s still confusing, I’d like to implement something similar to this. Notice how on the first page, the top header is large (roughly 500px tall). As you move onto subsequent pages, the header shrinks down to maybe 100px tall.

Thanks in advance.
