Hi @speck, thanks a lot for the read only link. May I ask, why you are needing a line-height of 100px? is it to add spacing in the menu? I would not use line-height to affect positioning of an element relative to other elements. Instead, I would use padding and margin to space your menu items and align those.
The interaction does not support changing the line-height, only the height of an element. If you use paddings and margins and height for your navbar, then the interaction should work better
I hope this helps, let me know if you need some help with the navbar.
