Css: can u have both an ID and class with in <ul> <li>?

[julie20099]

I've made buttons out of my nav bar.
I have inactive buttons and highlighted buttons but the problem is I can't keep them "highlighted" to represent "current page"

yes, you can most certainly have class and ID in your <ul> or <li> tags.
however, a specific ID can only be used once but a class can be used multiple times.
