Menu Size and spacing

How can I change Letters Size and Spacing between items?

Or there is other way to make the items be only in one line? Check http://lyaateliermistico.com as example.

Thanks!

Hello,

Please provide a more specific location where you want to change the styling.

The request is to generic and it seems like it falls out the support scope as it is impossible to provide all the letter size and spacing CSS codes…

All the styling is handle by this file:
