Thank you very much. Both options are exactly what i'm searched for.

Is it possible to do not convert headline styles to <h1> etc? rather as too?

Maybe you know also an option to assume text colors?

Tables with col spans and row spans are not converted correctly, but it think that's a really difficult topic - i think.

Check out the section of the manual about rendering math in HTML.
--mathjax might be the best option for you.
