How to delete the "Leave a Reply" link at the top of list of posts page

Hi everyone,

Apologies for what might seem to be an elementary question, but I am using a twenty twelve child theme and I am trying to get rid of the “Leave a Reply” link at the top of posts between the title and content.

I was able to do this successfully in single post pages with CSS:

.single .entry-header .comments-link { display: none; }

but in category pages and the main the “Leave a Reply” link remains at the top.

Is there a style.css fix to that? I’m really not sure how I would go about editing PHP in a child theme.

Thanks in advance for any help you can provide.
