Attachment

In Guide, for some articles I want to link to an article attachment in the body of the article rather than have the attachment shown at the bottom of the article. I know that in style.css I can hide displaying attachments for all articles:

.article-attachments {
  display: none;
  }

What I want is to be able to do the above but selectively per article without having to modify a conditional section in a hbs file with specific article IDs. Is this possible in the CSS?
