I want to separate the footnotes from other content by a horizontal line left aligned between content and footnotes.
I use in the before-field the CSS statement:
<hr style="width:150px; height:1px; text-align:left; line-height:100px;">
This shows always a line center aligned and the text line height definition is also ignored; and more: the line is not shown on all pages/posts having footnotes. I use the Atahualpa theme.
