JavaScript JavaScript and the DOM Getting a Handle on the DOM Selecting Multiple Elements

Why the code doesn't apply?

We have some JavaScript code that will cycle over list items and apply colors from an array called colors. The code will apply the first color to the first list item, the second color to the second list item and so on. But the code is not complete. On line 1 of app.js, set the variable listItems to refer to a collection. The collection should contain all list items in the unordered list element with the id of rainbow.

<!DOCTYPE html>
    <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>
    <script src="js/app.js"></script>
let listItems = document.getElementById('rainbow');
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

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

Close. But you need to target the li elements inside the #rainbow ul tag instead of the #rainbow tag itself.

let listItems = document.querySelectorAll("#rainbow li");
