Simple and easy footnotes, work as expected, easy CSS customization

The title says it all – this plugin does exactly what I want, and is easy to customize if you have a child theme. I did the following tuning to get smaller footnotes and a wider black divider:

sup.footnote a {
		  text-decoration: underline;
		  vertical-align: super;
		  font-weight: bold;
		  font-size: 80%;
		  padding-left: 0.3em;
		}

		.footnotedivider {
		  width: 40%;
		  padding-top: 0.8em;
		  border-top: 1px solid #000;
		}

		.footnotes {
			font-size: 72%;
		}

		.footnotes li {
		  line-height: 1em;
		}

Thank you!
