Create a horizontal navigation bar using flexbox. The items can stretch to fill the available width, or be spaced apart, and you can style the page any way you like.
Use semantic tags like
<nav> where appropriate. You'll also want a wrapper or some other kind of container to keep things at a reasonable maximum width. Make sure the page is flexible when you resize the window though!
Include about five items in your nav. For example, you can use: Home, About, Contact, Categories, Archives.
