Separating Line at end of posts.

Hi. Is there anyway to automatically add a dividing line at the end of my blog posts. The idea would be to separate the new text from the bottom controls. Thoughts? Thanks!

Hello there,

I hope you are doing well today.

You can use the following CSS code to add a border to the posts by going to Appearance > Customize > Additional CSS and pasting it there.

/*Post bottom border*/
.row {
    border-bottom: black 2px solid;
    margin-bottom: 10px;

Best Regards,
