}

@media all and (max-width: 500px) {

  #modal {
    width: 100%;
    height: 100%;
  }

}

JavaScript

// Query the DOM
var launchModalButton = document.getElementById('launch-modal'),
    modalBackground = document.getElementById('modal-background'),
    modal = document.getElementById('modal'),
    closeButton = document.getElementById('close-modal');

// Show Modal
launchModalButton.onclick = function() {
  modalBackground.style.display = 'block';
  modal.style.display = 'inline-block';
};

// Hide Modal
closeButton.onclick = function() {
  modalBackground.style.display = 'none';
  modal.style.display = 'none';
};
