I’m trying to add a logo image into my menu (i.e. as part of the main menu). However, when I look at it on the frontend, the menu items are aligned at the top of the image instead of the center.
Don’t really have enough info here to answer reasonably.
But to start, look at the full screen menu of this site – Weaver Xttreme. It is part of the main menu. So you mean something like that? Please be more specific, and provide a link to the site in question if possible.
The rule below can make all items the same height as the image (56px), center them vertically, as well as reducing/removing the existing vertical padding
