What
The burger mobile menu doesn't close on pressing escape key

Why
Edge case is not handled either in JS or CSS code

Fix
JavaScript code to close the modal

document.addEventListener("keyup", (event) => {
  if (event.keyCode === 27 && header.classList.contains("open")) {
    header.classList.remove("open");
    body.classList.remove("noscroll");
    fadeElems.forEach(function (element) {
      element.classList.remove("fade-in");
      element.classList.add("fade-out");
  });
  }
});

Also
Moving the code to close the modal into a function to maintain DRY

const closeModal = () => {
  header.classList.remove("open");
  body.classList.remove("noscroll");
  fadeElems.forEach(function (element) {
    element.classList.remove("fade-in");
    element.classList.add("fade-out");
  });
};

document.addEventListener("keyup", (event) => {
  if (event.keyCode == 27 && header.classList.contains("open")) {
    closeModal();
  }
});
