How to use parent/children node to get listItems to refer to a collection?

I've tried approaching this with the ElementsByTagName and the ElementById. I would think document.getElementsByTagName('ul') would work, but since it doesn't, I don't know how to access the list items.

js/app.js 
var listItems; 
var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

for(var i = 0; i < colors.length; i ++) {
  listItems[i].style.color = colors[i];    
}
const listItems = document.getElementById.ParentNode.children('rainbow');
index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Rainbow!</title>
  </head>
  <body>
    <ul id="rainbow">
      <li>This should be red</li>
      <li>This should be orange</li>
      <li>This should be yellow</li>
      <li>This should be green</li>
      <li>This should be blue</li>
      <li>This should be indigo</li>
      <li>This should be violet</li>
    </ul>
    <script src="js/app.js"></script>
  </body>
</html>

Hi Cody,

Either one of the methods you’ve listed would work. The thing is, that only gets you the unordered list element. You want the list items.

So after you grab the <ul> you want to chain the children property onto the end of it. Well, you don’t have to use that method, but it’s one way you could go about it.

So...

var listItems = document.getElementById(‘rainbow’).children

👆🏾 That statement says, “Target the element in the DOM with an id of rainbow and store all of its children in the variable listItems”.

Does that make sense?

If you need any more assistance, let me know.
