Answer 1

The classList was written classlist, fix the case and add style name as argument:

Object.classList.toggle(<style_name>)

https://developer.mozilla.org/en-US/docs/Web/API/Element/classList

I guess the toggle button will be better outside of sidebar div, so when sidebar pops the toggle button remain at its position.
