I have changed the H3 heading to include a horizontal line as I don't like the look of inserting a regular line and the subsequent spacing it creates around it. This works fine but somehow the top margin in the reading pane disappears:
I've tried to adjust the margin/border/padding but this does not make any difference to the first line - only subsequent H3 lines if that makes sense. Any idea how to fix this? Is there a separate CSS to define the reading pane borders?
border-bottom: 2px solid #eaecef;
/* font-size: 1em;
font-weight: 700; */
