I'm out of my depth here....a true noob...
I'm trying to figure out how to change the fonts on epubs I load onto my Kobo, i.e. override the built-in fonts that for me are too light, not black or contrasty enough.
I have a sense that this means altering or adding to the stylesheet for an epub, but that's as far as I've gotten.
I've used Calibre and just downloaded Sigil....but I don't see this capability or at least in any direct way...
Can someone point me toward the next step or offer other suggestions. Many thanks (from Toronto).
