Follow-up Comment #2, bug #623 (project tex4ht): Dear Michal,
aaah, I see. In fact, my problems were seen with TikZpictures, i.e. I'm the same guy from here: https://tex.stackexchange.com/a/641354/224985 The black pgfornaments became invisible with a dark theme for me by default, which confused me at first. I then tried with a colourful TikZ picture and saw the colours became inverted, i.e. I used: \tikzset{pgfornamentstyle/.style={color=black,fill=yellow, opacity=0.7, line width=0.5pt}}; \node[anchor=south]{\pgfornament[height=1.0cm]{87}}; within that example and the ornaments came up with a blue fill colour. But you are fully correct, it does not happen to \includegraphics. The CSS config you added works perfectly fine for me in the case of black TikZ images, it makes them visible nicely and the body and text are well adapted to the dark theme. So I think this is a large improvement to the default :-). _______________________________________________________ Reply to this item at: <http://puszcza.gnu.org.ua/bugs/?623> _______________________________________________ Message sent via/by Puszcza http://puszcza.gnu.org.ua/
