Add height rendering options? Or maybe full screen?

[insspb]

I am far far from front end CSS, maybe you can help me, or maybe we need an option for mermaid directive?

So long story short. I have a large erdiagram, that rendered too wide. (Screenshot)

New zoom function helps a little bit, but anyway user cannot understand anything, as diagram block has only 100 px of height. Is it possible to add option to specify height or, better, an option to show diagram on modal full screen window on click?
