CSS to highlight author comments

[ChrisRiley]

I am migrating from Blogger to Weebly, and want to bring my readers with me. I cannot use Facbook or Disqus in the comments, as some have expressed a disliking for them. So I'm stuck with the default, which I actually prefer. However, I want the blog author comments to stand out, so my replies don't get lost in the crowd.

There are plenty of articles online, how to make adjustments in Wordpress, under css.styling. But there don't seem to be any instructions for Weebly. I only want a simple change of background colour, for author comments.

Something along these lines:

commentlist .bypostauthor {background: #e7f1ec;}
commentlist li ul.children li.bypostauthor {background: #e7f1ec}

Only I don't know where to insert it, in the Weebly Edit HTML/CSS. The above code was taken from an article on how to make adjustments in a Wordpress site. I am familiar with that, as well as making changes in Blogger. The setup for Weebly however, is a little different. Any help would be appreciated.

We actually already style them differently; if you are logged into your Weebly account when you reply to a comment on your site, the reply will have a different background color. It varies a little depending on the theme, although if you don't like the color used by default it would still be possible to override with CSS.

I signed out as author, and did a dummy comment via the website. That's when I saw the two different colours present, for generic commenter and author. Thanks for pointing that out. If I did wish to change the colour on the author comments, what would I need to change in HTML/CSS? Thanks.

Can you post a link to a page that has comments on it from you? I can find the class by looking at the live site.
