How can I create a modal in an article that when opened, a different webpage will display in the modal

Hi Melody Quinn, I think first create the subscription page as you need with functionality and then wrap the link of the subscription webpage inside the iframe under the modal.

e.g.

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

  <!-- Modal content -->
  <div class="modal-content">
   <span class="close">&times;</span>


   <iframe src="URL OF SUBSCRIPTION WEBPAGE" height="200" width="400"></iframe> 


</div>
</div>

Good morning @Ifra Saqlain, this seems to be a good start, thank you! 

A couple of questions:

1. Is it possible to simply insert a modal into an article via the article html, instead of having an entire article template? 

2. I would want this modal only to open when a user clicked a button I put on the article, how do I achieve this?

Hi Melody, please follow the below steps to add a modal with another webpage.

1). Go to your article page and paste it at the bottom on the file.

<!-- Trigger/Open The Modal -->
<button id="myBtn">Open Modal</button>

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

  <!-- Modal content -->
  <div class="modal-content">
    <span class="close">&times;</span>
    <iframe src="https://URL.zendesk.com/hc/en-us" style="height:200px;width:300px;" title="Iframe Example"></iframe>
  </div>

</div>

2). Open your style.css file and paste it at the bottom.

/* The Modal (background) */
.modal {
  display: none; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  left: 0;
  top: 0;
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  overflow: auto; /* 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 */
}

/* The Close Button */
.close {
  color: #aaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: black;
  text-decoration: none;
  cursor: pointer;
}

.modal-content iframe{
  height: 100vh !important;
    width: 100% !important;
}

3). Open your script.js file and paste it at the bottom under the DOM function.

// 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";
}
}

Output is:

See the button -

when you are clicked this button- my homepage is open under the modal over current article

Hope it works for you.

Thanks

Add this part to your master page. In your page which will have the the control to open the modal, add this div. I am using Link Button to open the modal. This is how you can trigger the javascript function.

/* The Modal (background) */
.modal {
  display: none; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  left: 0;
  top: 0;
  width: 100%; /* Full width */
  height: 100%; /* Full height */
  overflow: auto; /* 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 */
}

/* The Close Button */
.close {
  color: #aaa;
  float: right;
  font-size: 28px;
  font-weight: bold;
}

.close:hover,
.close:focus {
  color: black;
  text-decoration: none;
  cursor: pointer;
}
