I am currently writing a processor to convert a specific website to EPUB and everything works fine except that the result I get, when read in Calibre does not look very nice I think.
I was looking for a CSS file to beautify the result but so far I have not been ale to is this thread Any opensource or free css stylesheets for books? but it dates back to 2016 and I was wondering if there was something more generic / up-to-date that could be used.
