User experience

A user opens the webpage and after 3 seconds the floating stage appears. The Floating stage offers additional video or other rich media experience. The Floating banner accommodate a link to the predefined landing page. The ad maintains this size until the “Close” button click. The ad expands as many times as the user clicks on the initial standard banner.

Creative assets

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

  • Video player needs a MP4/WEBM format videos 300x200px.
  • A poster 640x360px 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).
  • Screenshot 1098x1018px for floating stage (PNG/JPEG).
  • Banner assets 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

These are the values that can be changed:

"screenshot" - screenshot url. By default, it uses first additional asset assigned through Additional assets panel;
"alignX" - horizontal screenshot alignment (left/center/right);
"alignY" - vertical screenshot alignment (top/center/bottom)
"offsetX" - horizontal screenshot offset in pixels;
"offsetY" - vertical screenshot offset in pixels;
"direction" - defines screenshot's opening direction (top/right/bottom/left);
"gap" - defines gap between banner side and the opened screenshot in pixels;
"perspective" - animation perspective in pixels;
"rotation" - fully opened screenshot rotation;
"scale" - fully opened screenshot scale;
"clicktag" - banner's / video player's landing page landing page;
"target"- banner's landing page target;
"video" - setting different video parameters;
"sources" - video files;
"poster" - video poster. By default, it uses second additional asset assigned through Additional assets panel.
