Rich Media (HTML5) Web Ads Guide

What are Rich Media (HTML5) Web Ads?

Rich media Ads, also known as HTML5 Ads include advanced features like animations or other elements that encourage viewers to interact and engage with content. Rich Media ads are formatted using HTML5, 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 Flash, which is no longer supported by RollWorks or any of its partners.



What are the Zip file requirements for Rich Media (HTML5) Ads?

Check.png 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)

What are the technical requirements for HTML5 Rich Media Ads?

  • The maximum 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 = "";
    • This must be passed as a parameter to any event in the ad code.

      <div id="clickArea" style="width: 300px; height: 250px" onclick=" ,'_blank');">
