I can't imagine how the text gets unreadable with the default font settings.

okay, "unreadable" was a little bit over the top, but when you get older like me and have a high resolution monitor, then it is really hard. Look at the attached screenshot. This is large (18px)!! And above not black, but grey on white background!
For my old eyes very difficult to read.
Can you give me some code to add to the custom CSS box? Just like before ?
I don't want to take the Skin of Jeff, I like yours much more, only these typo things are a little bit difficult.
Kind regards
