It does only that you need to add window.onload = function(){ //code goes here } Like in this code: https://code.sololearn.com/Wj153VKGavW0/?ref=app

Javascript needs all html dom elements loaded before doing something with them. Enclosing your code like this: window.onload = function() { // your original javascript code } It means, when all html elements are created and loaded in my browser, I could reference them (adding event listeners, etc...)
