Hi, I'm trying to select all the element in a page that have the ".playableTile__heading" tag, but if i use just the querySelector it only selects the first element, and if i try using querySelectorAll the script doesn't load.

  let links = document.querySelectorAll('.playableTile__heading');
  //Using All makes the scipt not work

   links.style.background = 'red';
   //Testing to see if does any change to the page

Is there any way i could make this work? My final goal is to save an array with innerHtml of these elements.

document.querySelectorAll('.playableTile__heading').forEach(el => el.style.background = 'red');

This is better though https://pastebin.com/raw/0w0LXFhh
