Vertical non sliding header on the right side

Doesn't seem to narrow it. Can you please have a look?
Thanks

!important saved it.

Thanks and sorry :)

Glad you found the solution.

Hello once again. I am trying with this to change the menu font weight for active page and on hover.
Doesn't seem to work.
What am I doing wrong?

Hi there,

would you mind starting a new topic, as it makes it easier for everyone to search for them. Thanks

Thanks David,
I posted it here thinking that it all refer to the vertical header.
I will open a new one.
