Examples
Recommended default creative dimensions
Side Panels:
Width: 800px (100% width)
Height: 1440px (100% height)
Top Banner:
HTML5: width: 1280px (100% width), height: 180px (100% height)* (HTML Zip File or 3rd Party Tag)
Top Banner sizes vary across publishers and between countries, so please read carefully to ensure your assets are produced correctly.
For HTML5 Top Banners, the creative width must be responsive (width: 100%) up to a maximum width of 1280 pixels. The height will match the billboard height from the list below. If the width of your top banner is not responsive, there may be empty space visible between the top banner and side panels on some sites.

Format description and guidance
Fluid skins are a responsive high impact format, composed of three individual HTML5 panels - a left panel, a right panel (the side panels), and a top banner. The side panels fill the space between the sides of the page content and the window edge, and scale responsively with the height and width of the browser. The topbanner fills the gap between the side panels, above the page content. The content within each panel should scale responsively based on the width and height of the individual panels. For more information about building responsive creative, check out of Guide to Responsive HTML and building responsive creative guide.
All creative assets (images, videos, scripts etc) used by your banner must be included within the creative Zip-file. Linking to assets hosted on external severs is not permitted, and may result in your ad being blocked by some vendors. The only exception to this rule is for webfonts hosted by fonts libraries for licensing purposes, such as Adobe Typekit, Google Fonts, MyFonts etc.
Sticky video and the side overlays. When the creative is paired with the Skin Top with Sticky Streaming Video top banner, the video moves into the side panel once the top banner scrolls out of view. The Overlay Behaviour setting controls what the side overlays do while that player is on screen:
- Overlap (default) – the player is drawn on top of the overlays. Nothing moves, but the player can obscure overlay content on shorter screens.
- Resize While Sticky – the overlay container shrinks to the space the player leaves while it is on screen, and returns to full size when playback is handed back to the top banner.
- Always Reserve Space – that reduced overlay area is kept at all times, so nothing moves as the user scrolls.
Both reserving modes scale the overlays down rather than cropping them, so design overlay artwork to stay legible at around two thirds of its full height. The Overlay Container Gap sets the minimum space kept between the player and the overlays. Overlap is the default, so a creative only behaves differently once this is changed.

Getting hands on with responsive HTML5
Max total file weight
3.5 MB.
For best performance, all assets should be compressed and optimized to the lowest possible file weight.
Animation
Maximum of 5 loops.
Maximum animation time 30 seconds (may vary by publisher).
Asset type
Responsive HTML5 (either Adnami hosted by sharing a zip-file or served via 3rd party tags).
HTML must be minified and optimized for polite load.
Click tags and tracking
For Adnami hosted creatives, see our clicktags and tracking guide.
To enable video tracking metrics, see our API for measuring VTR guide.
For creatives hosted using 3rd party tags, use the appropriate click methods and trackers for that provider examples.
Other Requirements
Do not link to any files or scripts hosted on external domains. All assets used should be included within the creative zip-file, or hosted on Adnami domains. Linking to resources on non-approved vendors may result in ads being blocked by Google Ads Manager and DV360.
Audio
User-initiated.
Template Details

| Overlay Behaviour | Controls how the side panel overlays react to the sticky video player. Overlap keeps the original behaviour, where the player is drawn on top of the overlays and can obscure them on some screens. Resize While Sticky shrinks the overlay container to the space left by the player while it is on screen, and restores it when the player hands playback back. Always Reserve Space keeps that reduced overlay area at all times, so nothing moves as the user scrolls. The Overlay Container Gap sets the minimum space kept between the player and the overlays. | Overlap | choices: Overlap, Resize While Sticky, Always Reserve Space |
| Vertical Offset | Sets an additional vertical offset from the chosen position (px, %, vh). | 0 |
