Hey Douglas,

So on Task 1 of 1 : 

// This gets the element with the "navigation" id from index.html and stores it inside a variable called "navigation"
var navigation = document.getElementById("navigation");   


// This gets the children (the <li> items) of that same navigation element and stores it another var
var listItems = navigation.children;

For Task 2 of 2 :

HINT : You need to use the querySelector() method. Here is an example :

element = baseElement.querySelector(selectors);

Think about what the question is asking for.

It's talking about traversing which is moving between different elements in the document tree which is HTML tags in the DOM.

You want to be able to search for the children of an unordered list which is your listItems variable.

So turn this

var listItems = navigation;

into this

var listItems = navigation.children;

To further illustrate this, it is discussed two videos prior to the challenge in question, starting at about 6:45 of the lesson on Traversing Elements with Children.
