Thanks! She’s teething right now so I’m on about 3 hours of sleep. Not so fun.
Tough question.. I think giving the menu items custom classes is your best bet.
So give all menu items for one screen size a specific class, and the other menus another class.
Then hide the smaller screen menu items by default, and use media queries to display them and hide the others at 640px.
Let me know if that makes sense or not 🙂
