this question is about coffecup HTML editor:
I know how to set font-family in CSS or HTML, so this question is totally unrelated to that, what i want is to adjust the font, size and background color IN the code editor view, is there any posibility to that? even if it is changing code files or anything, I just find windows monospace default font very very unclear, and not be able to adjust the background is not helping either, thanks in advance

Try
"Tools"
"Preferences"
"Customization"
"Modify Highlighting"
