HTML5 interstitial build guide
HTML5 interstitial creative overview
An interstitial creative is an ad that floats on top of a publisher's page. It's also known as a floating or prestitial ad. This ad format allows flexibility. Because it isn't assigned to a fixed ad slot, it can be almost any shape or size, and you can place it anywhere over a publisher's content.
This guide walks you through the process of building an interstitial creative using the DoubleClick Studio HTML5 SDK. After you've built the creative, you can serve it in both desktop and mobile web formats.
