Format description and guidance
This template allows for the creation of a HTML5 seamless skin. The skin must be built as responsive HTML5 with the width and height set to 100%, so that it scales responsively based on the size of the window.
A central “content area” should be positioned in the horizontal centre of the skin, with the remaining space used for the skin content.
In order to ensure that the skin adapts correctly to the publisher page, use the code snippet below to fetch the width of the content area (window.contentWidth), and height of the top banner (window.topHeight):
const contentWidth = window.contentWidth || 1000,
topHeight = window.topHeight || 250;
Note - these variables are only available to creative uploaded to Adnami as a zip-file, third party tags must use static values that correspond to the publisher specs.
Structure your skin as show below:
If your top banner contains interactive elements (eg video controls, carousels, multiple clicktags etc), then it should be built as a separate banner (that will be overlaid on top of the skin). Otherwise it can be incorporated as part of the skin.
