Change the cell size

Hello everybody,

I am a beginner, and I am wondering if there is a way to make this red space in the picture smaller in JupyterLab, or to change the size of the cells maybe, any solution to be able to display more code but by keeping the split view.

I am thankful for any hint.

Welcome :wave: You can change margin overrides in Settings → Settings Editor → Side-by-side left/right margin override:

These can even be negative if 0px is not enough.

Thank you very much :slight_smile:
