[Resuelto] Remove space between flags in the top menu

Background of the issue:
I am trying to adjust the spacing between flags in the top menu of my site enlace oculto. It looks like the Menu language switcher uses the same space as the menu items. I want to reduce the space to match the preview. Additionally, in the mobile version, the flags are stacked, and I want them to be in line.

Symptoms:
The space between flags in the top menu is too large, and in the mobile version, the flags are stacked instead of being in line.

Questions:
How can I reduce the space between flags in the top menu to match the preview?
Can the flags be aligned in line in the mobile version instead of being stacked?
