I have the following modal working,

on my site. It\'s exactly what I want in terms of ease of use, and function.

Answer 1

just write these lines in your head tag

$(document).on('keyup',function(evt) {
  if (evt.keyCode == 27) {
    location.href="#close";
  }   
});

Answer 2

For this you will need a little javascript. Check the code with some comments.

function modalClose() {
    if (location.hash == '#openModal') {
        location.hash = '';
    }
}

// Handle ESC key (key code 27)
document.addEventListener('keyup', function(e) {
    if (e.keyCode == 27) {
        modalClose();
    }
});

var modal = document.querySelector('#openModal');

// Handle click on the modal container
modal.addEventListener('click', modalClose, false);

// Prevent event bubbling if click occurred within modal content body
modal.children[0].addEventListener('click', function(e) {
    e.stopPropagation();
}, false);

Note, that closing modal is technically possible with CSS/HTML only, however for handling Escape key press you will need Javascript.
