How do I put a blank line above the “I recommend this” WordPress Plugin

The “I recommend this” WordPress Plugin adds a line at the bottom of each post with its thumb or heart, and the text line related to it.

Unfortunately I find that there is no space between the last line of the post and this plugins wording.

To change this, and leave some space between the post and the plugin instruction, I asked this question:

How do I put a blank line above the “I recommend this” WordPress Plugin ?

And the simple answer is:

Add this code to the CSS file in the child theme.

.dot-irecommendthis {
   margin-top: 10px;
   padding-top: 10px;
   border-top: 1px solid #CCC;
}
