Comment Count Custom CSS

Hi,

I want to remove the comment counts from the thumbnails on the homepage.

So I’ve tried customizing the CSS but nothing happens. I’ve tried two sets of code, but neither work.

I went to CUSTOMIZE > ADDITIONAL CSS

I tried this first:

.below-entry-meta .byline, .below-entry-meta .comments {
display: none;
}

and then I tried this

.comment-meta {
display: none;
}

But neither worked.

Any help with this would be great.

Thanks in advance
