I am developing a javascript-rendered mobile web interstitial. The layout is fully responsive, hence it will take 100% of the provided screen\iframe.
I now wish to display the interstitial through DFP.
At first I created a sized ad unit (320x480) and it worked just fine, but the interstitial was limited to the boundaries of the iframe.
I founf a new line item type called Out-of-page. The documentation states that:
They may include pop-ups and floating line items and are sometimes called interstitials.
But when I try to embed the interstitial in a test site, what happens is that the iframe stays 1x1, making the interstitial invisible (if I manually enlarge it with a debugger, I see it)
My settings:
- line item with inventory sizes of 1x1 and out of page
- creative with my code snippet
- ad unit is defined as size 1x1
I read in the documentation that:
If you're using a DoubleClick tag creative, you must ensure that the creative code trafficked on the other end of the DoubleClick tag (i.e., another DFP network) is properly coded for an out-of-page ad unit.
What does it mean, in terms of DFP Out-of-page interstitial, that the ad is "properly coded"? How do I force the interstitial to take all the size of the screen?
