JavaScript and the DOM code challenge

I'm stuck on this challenge. The goal is to loop through an array of colours and format each list item to match each colour. In the output preview it looks perfect but when I submit the code it returns an error: "Bummer: Did you select all 7 list items?"

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

for(var i = 0; i < colors.length; i ++) {
  listItems.children[i].style.color = colors[i];    
}
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 nivert,

you are very close...

And actually the way you did it works - it just is not how it is asked to be solved. ;-)

The task is to set the variable listItems to refer to a collection immediately, so you don't have to use "children" further down below...

So you want to use querySelectorAll to select all list items directly, not querySelector. Remember you can chain selectors to target all list items, like for example:

var yourVariable = document.querySelectorAll("#main-text p span");

Can you figure it out with this hint? ;-)

Let me know if not!

Blessings from Berlin and happy java-scripting, Nils
