Dash Bootstrap Components

I am using the dash bootstrap components to style the layout
I have no idea how to remove the gap between the two columns.
Attached are the figures of code and result.

it’s a little hard to read you code via the png file, but it appears you are specifying width=6 for the first column. If the component within is not 6 columns wide, you will have a gap.

Thank you, will chekc that out.
