 # A Basic Header
 
-Use flexbox rules to create this very common webpage header style. The benefit to using flex here is that everything should be _flexible_. Check out the two screenshots below to get an idea for how it should scale with your screen. Besides flex rules, you'll also want to add some rules for margin and padding. (hint: `ul`s have some default margin/padding that you will need to deal with)

 For this one you will probably need to edit the HTML a little bit. Often with flexbox you need to add containers around things to make them go where you need them to go. In this case, you probably want to separate the items that go on the left and right of the header.

 Flexbox is useful for laying out entire pages as well as the smaller components we've already been working with. For this exercise, we're leaving you with a little more work to do, with some things you may not have encountered yet. It's perfectly acceptable to google things you're unsure of!
 
 ### Hints
-- you may want to search something like `CSS remove list bullets`.  We've done this for you in previous examples, but not here. Yay learning.
-- We've added `height: 100vh` to the `body`.. this makes the body exactly the same height as the viewport. To stick the footer to the bottom you will need to use flex and change the direction to column.
