Add Top Menu Plugin – Issue/Questions

URL: https://www.leadonvalesolutions.co.uk

Hi, this one’s aimed at Richard Bonk – grateful if you can help.
Firstly, thanks for the above plugin. I’ve installed/activated and it’s working though:
1. A large space has appeared below the main nav menu – I need to move back up.
2. Is there a way to reduce the size of the font for the top menu? I see it’s using the same CSS as the main nav menu (I previously added, following forum advice, to the custom CSS box to sort spacing).
3. I would like to reduce the space between the top menu – please help with CSS.

Thanks very much, Bruce
