Apply Custom CSS to "All Category Pages Only"

Hello

I have been supplied the following CSS from a misunderstood question

#author-bio-box {
display: none;
}

The request was for to remove the 3rd party author box from my category pages only. However, I have been supplied with CSS that removes my 3rd party author box from the whole website including posts, pages, everything

I only want this to apply to my “Category Pages” Only

The reason I want this is because I am using a 3rd party author box plugin. But for some reason it is showing in my “Category Pages” I’s should not be showing in these pages such as

category/technology/

I do not know why author box is showing in the category/technology/ like this

Hoping someone can supply me with CSS code to remove the 3rd party author box from these category pages only. And have them “Remain” in my post pages.

My last forum question mentioned I wanted it removed from category pages only. But I was provided with ‘Global” CSS for all pages on site.

Can someone please help me urgently. It is just one tiny thing that I stopping me from going live and I am past my launch date.

If I can get this fixed I can finally put this on my live domain. This is only thing holding me after all this time
