<nav> instead of <div>?

Very novice question: I read that HTML5 allows for nav, footer and header tags. Do these have any specific properties that allow for creating navigation/footer/etc without having to change as much CSS as if one did it manually with a div?

Thank you for any help!

Hey,
Nope they are just tags you will need to add in manually your styling.
You could use Bootstrap to do that.
