Google Classroom Send button font shouldn't be affected

Doesn't make the whole page dark, only the background and not the document. However, it is still easier on my eyes than the page being all white.

Thanks man appreciate the port, was going to do it myself but figured someone had already done it.

Works like a charm, would really benefit from having the cursor visible when using the "grey mode"

Works like a charm, thanks!
One little thing, comments in Google Docs are still white, could this maybe be fixed at some point?

I'm only rating 4 stars instead of 5 due of me having issues seeing where my cursor is when i activate both options on google docs. (to have grey mode), other then that. This is great! https://imgur.com/a/Q5logug

Its really good! The only problem is that page is still white while everything else is dark. Other than that it works perfectly

This only changes the interface around the page, not the document itself, but if you go into File > Page Setup you can change the page background to black and then the text color to white. Works great for what I was looking for; probably the only thing I wish is that there was a lower contrast version, but with a pretty simple workaround, you get what you ask for.
