Apparently you can’t use window.onload() in multiple Javascript files. Instead of that, we can just use the load or DOMContentLoaded event and create a listener for that to run the function. I used this as a reference.

function base_onload() {
  blink = document.getElementById('blink');
  header = document.getElementById("header");
  progress = document.querySelector('#progress');

  h = document.documentElement;
  b = document.body;
};

window.addEventListener('DOMContentLoaded', base_onload);

this is a sample snippet
