this is really a very inconsequential question, I'm just curious.
This is a comment on KOTH: A world wide pandemic:
At least to my browser's rendering engine, there's a fairly clear difference between the struckthrough text and the other text: both font style and font size.
As we can see, the comment's HTML attributes and CSS classes are identical to the one immediately preceding it.
What's going on here, and how can I post comments in fancy fonts?
