The nuclear option for when a page does not have a dark mode

README.md

Nuclear Dark Mode

Open the browser console and paste the contents of nuclearDarkMode.js inside it.

Known bugs

• iframes apparently cannot have their styles set by the host page, and are instead removed entirely. Some pages have content in iframes.
• pseudo-elements may still have bright background colors. Is there a reasonable way to fix this?

nuclearDarkMode.js

var nuclearDarkMode = (root = document, seen = {}) => {
  if (seen[root]) {
     return;
  }
  seen[root] = true
  var items = root.getElementsByTagName("*");
  for (var i = items.length; i--;) {
      var item = items[i]
      item.style["background-color"] = "#222"
      item.style["color"] = "#eee"
      if (item.nodeName == "IFRAME") {
        item.parentNode.removeChild(item)
      }
    	
      nuclearDarkMode(root, seen)
  }
}
