Hi, I get stuck on this question and I need to continue finish the course, where I can get help with?

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[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>

Hi Jiayu,

There are several ways to write code that would satisfy this challenge, but the issue you’ve run into is that the challenge has asked you to return a collection of <li> elements, and not just a <ul> with an id of rainbow. 

var listItems = document.getElementById("rainbow").querySelectorAll("li");

The above code is a solution that would work, but again there are others solutions that would do the same thing.
