Hide blue box around code during slideshow of a Jupyter Notebook

Question

I am preparing a presentation in Jupyter Notebook (version 6.1.4, not Lab)

(not the final notebook, just an example) I also hide the code through a nbextension.

When I go into the slideshow (RISE), though, and arrive to the code cells, there is always the blue box around input-output.

Is there a way to hide or disable it in slideshow mode?

Or do I have to write everything in markdown somehow?

Answer 1

Just export the slides to html using the no input option:

jupyter nbconvert YOURNOTEBOOKSNAME.ipynb --to slides --no-input serve
