Replace stars() at last line with: onload = stars; Why↓ https://www.sololearn.com/post/90825/?ref=app JME Explained it well too. Please remember to use search bar 🔍 feature next time to prevent duplicates. This question is frequently asked!! Nice code btw. _K_ I was talking about Sololearn's seach bar. Anyway I'm glad you solved your issue.

Adding to what JME said, the most preferred way to wait until the DOM has finished loading is window.onload = function() { // Your code } And through jquery $(function() { // your code })

It has to do with sololearn running js before html Dom is fully loaded. You have to delay stars until Dom is finished loading so you can properly access document elements. A simple timeout is one way setTimeout(function(){stars();},10) Jquerys $( document ).ready() is another
