The script attempted to modify a div’s background color using document.body.removeChild, but as the script was loaded in the HTML head, the DOM had not loaded
Isn’t that how it works/always worked? When i was learning html/js ages ago i had to use some event listener (DOMContentLoaded i think) or put the script just before </body> (for any code that should run on load and interacts with the DOM).
And how do you change the background by removing a child?

The removed child could also have a background color, and it could span the entire area of the parent element.
But it’s weird because the quote says “modify a div’s background color”, and this way you don’t actually modify that, but only it’s appearance.
Or maybe it’s done with some CSS trickery, looking for a specific child in it’s selector?

Yeah, they should be listening for an event, not just YOLOing it in the head, that’s just racey…
