A complete HTML fragment inserted into the page using the iframe tag.
The author of the code is responsible for the ad displaying and working correctly across all major including their mobile versions.
The file type
HTML5 banners must be delivered as a standalone .ZIP archive.
An HTML5 banner archive (.ZIP) must contain a main file with the “.html” extension (index.html) and any other files necessary for proper rendering of the banner. All files and directories have to be stored in the root of the archive.
Supported file types
The allowed file types in an HTML5 banner archive (ZIP) are listed below:
Number of files
The file count in the HTML5 banner archive must not exceed 40 files.
The total data size of HTML5 banner is determined by the size of all the files after packing into a ZIP archive.
Loading data from external sources
Additional loading of data from external sources is not allowed, excluding only some supporting libraries stored on CDN servers.
Allowed external sources are:
When loading those support libraries, the script adress must start with “https://” (see example below).
There is only one URL allowed for redirecting from an HTML5 banner.
<a href="http://www.domena.cz" target="_top"> <div id="rectangle"> … </div> </a>
- There can only be one file with the ".html" extension in the banner archive.
- Filenames in the banner archive must not contain special and accented characters. If the banner is generated by an external application (Adobe Edge Animate, Google Web Designer), it is necesarry to make sure there are no special or accented characters present in the layer/object names before exporting the banner.
- Animated HTML5 banners must not use too many of the user's system resources. If the advertisement is using too many system resources, browsers may automatically block it and won't display it.
To make working with HTML5 banners easier, name each ZIP archive as follows: HTML5 + size + nameOfTheBanner (ex.: HTML5_970x210_leaderboard.zip). This will also significantly speed up the process of deploying a banner to the advertising system.
