Line after post issue

Hi!

I have a trouble with removing line that appears after post comments.

I need to remove this one (line, that appears after ❗ last comment ❗ ) via custom CSS & JS:

I know that this line is in PostStream-item class, but if I remove that class, all comments will disappear.

What should I do to solve this problem?

P. S.

Please note: the number of comments in each topic varies.

.PostStream-item, as its name suggests, is the whole item. The border is a border-bottom applied to it.

You should be able to hide it with something like:

.PostStream-item {
    border-bottom: none;
}

This will remove the borders under all posts. I guess you already have the selector for the last item ? Just merge what you have with my suggestion ?

clarkwinkelmann Fantastic! Many thanks for your help!

Any suggestions?

EDIT: SOLVED!
