Passing rendering params

[eysegal]

In native advertising, there is high importance for ads to appear as the same look and feel of the site which they are displayed.
Since the render url is registered on the advertiser side, how can we pass rendering signals when rendering the ad at the publisher?
Passing the publisher name or domain would probably be enough.

Thanks for raising this! Native advertising is indeed something that we are keeping in mind as we solve for more ads use cases while using fenced frames.

In the current state however, if you are using urn based iframes to render the ad, you can get the information from the embedding site via various means:

• location.ancestorOrigins if the domain is sufficient information, or
• using postMessage to communicate from the embedding site to the iframe or
• using deprecatedReplaceInUrn : This also works in fenced frames.

Thanks. Is it safe to use deprecatedReplaceInUrn? Looking at the name it seems to going to be deprecated.

We are working out the timelines for deprecatedReplaceInUrn and will be sharing that in the coming days.

In addition to issue #741, we are concerned that the current solution does not provide a comprehensive resolution for native ads.

Presently, when rendering a native ad, it is encapsulated within the HTML and styles of the publisher, with many styles inherited from the hosting site, mostly without our awareness.

Given that the protected audience winning ad is rendered within a fenced frame/iframe, we would need to apply all styles from the containing HTML page to the fenced frame/iframe.

In essence, the question is whether it would be possible to propagate the external HTML page styles to the internal fenced frame/iframe?

[eysegal]

The question above is important, @shivanigithub @JensenPaul do you know what's the answer?

No, it is not possible to automatically have styling information from the publisher page flow through to any kind of cross-domain frame. This is not about Fenced Frames or Protected Audiences in particular; the thing you're asking for is inherently not possible today in iframes either.

[eysegal]

Thank you for you response. Do you have an idea how we can support Native advertising where the fonts and other types of styling are inherited from the publisher?

What about using postMessage via SafeFrame and having the browser enforce CSS styles only?
