Stack Overflow: auto-close sign-up modals

Automatically removes the sign-up and login modal popups along with the dimmed backdrop that blocks the page.

Code to copy

/* Auto-dismiss the sign-up / login modal popups */
(function () {
  function close() {
    document.querySelectorAll('.s-modal, aside.js-signup-modal, .js-login-modal').forEach(function (m) {
      m.remove();
    });
    var overlay = document.querySelector('.s-modal--backdrop, .js-modal-backdrop');
    if (overlay) overlay.remove();
    document.body.style.overflow = '';
  }
  close();
  new MutationObserver(close).observe(document.body, { childList: true, subtree: true });
})();
