Pop up Modal that activates on multiple buttons

Right now ive got a pop up modal built with ID’s so i can only open that modal with one button however i want to use the same modal on multiple buttons across the page. i think i have to do this with classes rather than ID’s but i dont know how to recode the script to fit this

here is my html

<button id="myBtn" class=" btn btn-light">
click here

    <div id="myModal" class="modal">
        <!-- Modal content -->
        <div class="modal-content"> <span class="close">&times;</span>
            <?php echo do_shortcode(); ?>

here is my css

 .modal {
     display: none;
     /* Hidden by default */
     position: fixed;
     /* Stay in place */
     z-index: 35;
     /* Sit on top */
     left: 0;
     top: 0;
     width: 100%;
     /* Full width */
     height: 100%;
     /* Full height */
     overflow: hidden;
     /* Enable scroll if needed */
     background-color: rgb(0, 0, 0);
     /* Fallback color */
     background-color: rgba(0, 0, 0, 0.4);
     /* Black w/ opacity */
 /* Modal Content/Box */
 .modal-content {
     background-color: #fefefe;
     margin: 15% auto;
     /* 15% from the top and centered */
     padding: 20px;
     border: 1px solid #888;
     width: 80%;
     /* Could be more or less, depending on screen size */
     max-width: 800px;
 /* The Close Button */
 .close {
     color: #aaa;
     float: right;
     font-size: 28px;
     font-weight: bold;
 .close:focus {
     color: black;
     text-decoration: none;
     cursor: pointer;

here is the java 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";

any advice would be appreciated

So that’s a class, rather than an id. Invent a class name, and apply it to your buttons.

If the event target’s classList contains yourclassnamehere, the modal’s style display is set to block.

(Hint: I have structured that sentence and used those specific words for a reason.)

ive invented a class and used the getElementsByClassName and it didnt work at all

I didn’t put getElementsByClassName in my sentence :wink:

I used those words very, very specifically…


If the event target’s classList contains yourclassnamehere , the modal’s style display is set to block .
if ( event .target .classList .contains( "yourclassnamehere" )) { modal .style .display = "block" }

im going to be honest here i dont understand :joy: i dont know alot of javascript

Take the line of code in the spoiler, and put it inside the window.onclick function, after the end of the first if.
