PLAYGROUND ads are unlike most other ad formats that fit within a single box. Our ads are quite literally outside of the box. Our ads typically consist of a number of components called documents. These documents use Iframes on the host page to display in different positions. A good example of this is a Side Push which comprises five documents.
The HTML tab references each of these iframes through a special xyz-component tag on a div. Anything within this tag is placed within its iframe.
The CSS is copied into every document. ie every CSS class/id is available on all iframes. You can re-use classes or have unique class names to target a specific element within a document.
