This is a highly customizable and very easy to use animated Double Open Door template for Desktop non responsive sites.

User experience

The format consists of an initial 1000x200 stage and a floating 1680x800 stage. On the initial visit, the 1000x200 stage is displayed. On rollover after countdown, a floating stage with door experience appears and displays an active screenshot of initial website in the left side of the screen, screenshot of a landing page in the right side and a video stage in the middle.

Creative assets

The following items are to be delivered by a creative agency:

  • An asset for initial stage banner that could be a 1000x200 image or HTML5 file. The banner can be adjusted to your custom size - just change the width and height of the banner.
  • Video player needs a MP4/WEBM format videos.
  • A poster for the video, if there will be a video wall (the wall will be black before
    playing the video if no poster will be provided).

  • In case that browser is very old and doesn't support HTML5 the backup image (PNG/JPEG) is required (set in additional assets).
  • Banner asset containing manifest.json file and HTML file zipped together with images, scripts and other material.

NOTE: manifest.json file and HTML file should be in the root directory of the .zip file.

Customizing the banner

The file “index.html” can be adjusted to customize the banner components.

NOTE: In order to use Adform components for HTML, it is necessary to define global preloadQueue array, where you push all the wanted components to preload before script execution and to load Adform.DHTML.js

INFO: Please refer to the Video Player component for more detailed information on component setup and behavior.
