HTML5 creatives must meet the IAB standards for HTML5.

Your HTML5 creative must also meet these requirements:

  • All code needed for the creative (HTML, CSS, and JavaScript) must be compressed into a single ZIP file. If your HTML5 creative is already a single HTML file, you must zip it prior to sending.
  • The primary HTML file must be in the root directory of the ZIP file. If there is only one HTML film (*.html or *.htm) in the ZIP file, it is considered the primary HTML file. If the ZIP file contains multiple HTML files, the primary HTML file must be named "index.html".
