How to make custom native interstitial ads
Interstitial ads are pop-up ads that take up the viewer's screen for a few seconds before giving way to the content on a page or app. It can be as large as the entire viewable area of a page or app. You can use native templates to create interstitial ad items that are tailored to your needs.
If you'd rather sanitize the template and have only HTML inside it, you should make your interstitial ad using a styled native ad template instead. For more information on the differences between custom native ads and styled native ads, read About native ad templates.

How to create a custom interstitial ad template
This template will require the user to provide the URL to where the image creative is hosted when creating the interstitial ad item.
- Click Templates in the left navigation menu. The Templates section will appear.
- Click Native Ad Templates. The Native Ad Templates subsection will appear.
- Click Add Native Ad Template. The New Native Template window will appear.
- Click Custom Rendering/API. The New Native Ad Template page will appear.
- Name the template then add an image URL variable for the image that will be in the ad. In our sample code we called this variable ImageURL.
- Enter the code in the HTML Template (Custom Rendering) field, then click Save Changes.
Here's the code we used in our example:
<!DOCTYPE html>
<html lang="en">
<head>
<style>
.interstitial-container {
position: fixed;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
z-index: 1;
background-color: rgba(0, 0, 0, 0.25);
display: flex;
align-items: center;
justify-content: center;
}
.interstitial-image-container {
position: relative;
}
.interstitial-image-container a img {
width: auto;
height: auto;
max-width: 100%;
max-height: 100%;
}
.interstitial-close-button-container {
position: absolute;
top: 15px;
right: 15px;
cursor: pointer;
}
.interstitial-close-button {
width: 26px;
text-align: center;
display: inline-block;
color: #ffffff;
font-size: 22px;
background: #000000;
border-radius: 26px;
user-select: none;
}
</style>
</head>
<body>
<div class="interstitial-container">
<div class="modal-content">
<div class="interstitial-image-container">
<a target="_blank" href="[TRACKING_LINK]">
<img id="image" src="[%ImageURL%]" onload="adjustContainerSize()">
</a>
<div class="interstitial-close-button-container">
<span class="interstitial-close-button" onclick="closeButton()">×</span>
</div>
</div>
</div>
</div>
<script>
function adjustContainerSize() {
const image = document.getElementById('image');
const container = document.querySelector('.interstitial-container');
if (image.complete) {
container.style.width = `${image.width}px`;
}
}
function closeButton() {
document.querySelector('.interstitial-container').style.display='none';
}
</script>
</body>
</html>
