Modal avec pdf incorporé

Question

J'essaye de mettre un modal sur un site Web que je fais qui a un pdf incorporé.

Le pdf apparaît vraiment petit. Je n'ai pas écrit ce code à partir de zéro. Je l'ai trouvé sur un autre site. Quelqu'un peut-il aider? J'utilise le framework Zurb Foundation, FYI.

HTML ----

<section class="modal"> 
      <div class="wrap row small-up-1 medium-up-1"> 
       <div class="special column"><h3>Modal</h3> 
        <!-- Trigger/Open The Modal --> 
         <button id="myBtn">View Full Menu</button> 

         <!-- The Modal --> 
         <div id="myModal" class="modal"> 

         <!-- Modal content --> 
         <div class="modal-content"> 
          <span class="close">x</span> 
          <iframe src="pdf.pdf"></iframe> 
         </div> 
        </div> 
       </div>    
      </div> 
    </section> 

Javascript ---

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

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

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

// When the user clicks on the button, open the modal 
btn.onclick = 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"; 
    } 
} 
</script>
