Why we always use to make Navigation why not ?

Question

Why do we always use

to make navigation why not
? While we can use both technically.

Answer 1

Because semantically ul makes more sense if you don't care about the order of menu items.

If you need items to be somehow numbered or when the order has meaning, then we use ol.

If you're not interested in semantic markup but only in appearance, you can use either. Or even neither, use divs and spans and anything else to achieve the needed appearance.
