JavaScript

// Get the modal
var modal = document.getElementById('myModal');

// Get the button that opens the modal
var btn = document.querySelectorAll(".bookbox");

// Get the <span> element that closes the modal
var span = document.getElementsByClassName("close")[0];

// When the user clicks on the button, open the modal 
[].forEach.call(btn, function(button) {
	button.addEventListener('click', function() {
   modal.style.display = "block";
  });   
});

// When the user clicks on <span> (x), close the modal
span.onclick = function() {
    modal.style.display = "none";
}

// When the user clicks anywhere outside of the modal, close it
window.onclick = function(event) {
    if (event.target == modal) {
        modal.style.display = "none";
    }
}
