What are HTML5 ads
HTML5 ads, also known as rich media ads, include advanced features like animations or other elements that encourage viewers to interact and engage with content. These ads are formatted using HTML5 language, which allows developers to add animations directly into the source code of a page.
These types of ads are like mini web pages and contain multiple file types that can combine HTML, Javascript, CSS, Web Fonts, shared javascript libraries, SVG, WebGL, and other standard assets, such as images. This eliminates the need for plugins like Adobe Flash, which is no longer supported by RollWorks or any of its partners.
Zip file requirements
✅ The maximum zip file size is 150KB.
✅ Each HTML5 ad must be its own zip file that contains all code and assets (including public, commonly used JavaScript libraries). It must contain all files referenced from the HTML document:
- Root of the folder should be a single, well-structured, and complete HTML document
- The ad must be loadable into an iFrame (when being served).
- Supported Shared Libraries: Adobe Edge, CreateJS (Easeljs, Movieclip, TweenJS, SoundJS, and PreloadJS), JQuery, Angular JS, Tumult Hype, Swiffy, GSAP (TweenLite, CSSPlugin, and EasePack).
✅ Links must reference file locations.
✅ Assets must be loaded securely using https.
❌ Code references to external domains are not permitted (no cross-domain scripting).
❌ Local storage or session storage libraries are not permitted.
❌ CDN calls are not allowed within the creative's HTML file due to security reasons.
Technical requirements
- The maximum zip file size is 150KB.
- The animation limit for an HTML5 ad is 30 seconds. Looping the animation is not allowed.
-
Use the <!DOCTYPE html>, <html>, and <body> tags
-
Use the <meta> tags to identify the size of the ad:
-
<meta name="ad.size" content= "width=300, height=250">
-
-
Declare a clickTag variable. ClickTag is a click-through URL: a shortcut to set the click-through URL in the platform.
-
<script type="text/javascript">
// Change the value of this string to your URL
var clickTag = "https://www.adroll.com";
</script> -
This must be passed as a parameter to any window.open event in the ad code.
<div id="clickArea" style="width: 300px; height: 250px" onclick="window.open(clickTag ,'_blank');">
