Modal with cookie?

[RossF1984]

Hi,

I have used some code for a Modal on my site. However I would like this to use a cookie so that it doesn't show every time someone comes to my page. Is this possible to do?

Apologies if this seems a silly question but I am very new to all of this....

My code is currently as follows:
 

<meta name="viewport" content="width=device-width, initial-scale=1">
<style type="text/css">body {font-family: Arial, Helvetica, sans-serif;}

/* The Modal (background) */
.modal {
  display: ; /* Hidden by default */
  position: fixed; /* Stay in place */
  z-index: 1; /* Sit on top */
  padding-top: 200px; /* Location of the box */
  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 */
.modal-content {
  background-color: #fefefe;
  margin: auto;
  padding: 20px;
  border: 1px solid #888;
  width: 60%;
}

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

.close:hover,
.close:focus {
  color: #000;
  text-decoration: none;
  cursor: pointer;
}
</style>
<h2><!-- The Modal --></h2>

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

<p style="text-align: center;"><span style="font-size:24px;">Introducing.....</span><br />
<br />
<img alt="" src="/images/source/Hairshark-logocrop.png" style="width: 349px; height: 77px;" /></p>

<h2 style="text-align: center;"><span style="font-size:24px;">The worlds most advanced volumising backcombing tool.</span><br />
<br />
<img alt="" src="/images/source/HairShark/hsbrush.png" style="width: 200px; height: 179px;" /></h2>
</div>
</div>
<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 <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>

You might be able to use localStorage with this.

Let me know if you need more assistance.
