Not all advice I give is perfect, or so Dr. Drang found out.
A lot of blogs that use footnotes don’t correct for a line-height issue in thier CSS — leading to footnoted lines having a greater top margin and thus looking bad. I forget who told me this, but I did not figure it out myself — so thanks to that person.
Drang implemented my fix and found that it didn’t play well with iOS, so he has a modified fix. For what its worth, I haven’t seen the issues that he has on iOS — but it his fix does appear to work.
