Please provide me the solution.

What is wrong with my line 1 in app.js?

<!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>
const listItems = document.querySelector('#rainbow');
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

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

Right now you're selecting the list itself, the <ul>, you want to select the children of the list, the <li>, notice that only the ul tag has the class rainbow, which is what the selector is pointing to now.

Instead of selecting just the <ul> element, you need to select all of its children. You can do that by using querySelectorAll and targeting the <li> elements of #rainbow

1 Answer

You need to update your selector to target the li's, not just the parent element.

const listItems = document.querySelector('#rainbow > li');

Also, querySelector() only selects the first matching selector, so you'll need to use querySelectorAll().

const listItems = document.querySelectorAll('#rainbow > li');

Good luck!
