The fluid skin format consists of three separate elements - a left panel, a right panel (the side panels), and a top banner. You can use either images or video as the background asset of each element. For best results, combine with a PNG overlays, to create a simple responsive skin. For skin designs with artwork that spans across the entire screen, consider using our seamless skin format instead.

- Video - 1080x1920px (9:16) MP4 (Optimised for web)
- Image - 800x1440px JPG
Overlay: Up to 800x1440px (PNG with transparency), for best results avoid exporting overlay assets with any excess white space, and instead set the size and position within the template.
Background: 1000x180px* (MP4 or JPG)
*Default Top banner dimensions vary by country:
- 🇩🇪 DE: 970x250px
- 🇩🇰 DK: 930x180px
- 🇫🇮 FI: 1000x400px (1280x400px for iltalehti.fi)
- 🇳🇴 NO: 1000x300px
- 🇸🇪 SE: 1000x240px
- 🇬🇧 UK: 970x250px
Top banner width may vary from publisher to publisher. Always confirm specs with the publishers on your plan before creating skin assets.
There are multiple templates and options available for the top banner, including third party tags and custom HTML5 zip upload.
Format description and guidance
We advise using the new Fluid Skin Responsive Side Panel template for the left and right banners.
Background assets use the “cover” scaling mode by default, so be aware that the edges may appear cropped for different screen sizes and resolutions. You can set the anchor point of the background via background position - this is the transformation point around which the image will be scaled, and it will be the part of the asset guaranteed to be in view, so make sure to set it to an appropriate value for your specific assets.
Overlays appear on top of the background asset, and should be used for essential static brand elements (eg logos, messaging, CTA etc). The overlay uses the “contain” CSS behaviour, so will never be cropped. The width and height of the overlay are flexible, you can define a percentage of the total side-panel width/height the overlays should occupy, as well as define minimum and maximum widths (in pixels) to constrain their scaling if you so desire.
You can also set how the overlays are positioned within the skin side-panels. By default they are centered, however you can choose which side or corner they should be anchored to, as well as offset the position on the X or Y axis (custom X/Y position). Custom position offsets will be added to whichever side the asset is positioned from, eg if an overlay is positioned at the bottom, an Overlay Custom Y Position of 10px will set the overlay to be 10px from the bottom of the skin. You can use any valid css unit eg 250px, 50%, 20vh etc.
For best results, export the overlay PNG assets without any excess empty space - this allows the template to handle the overlay scaling and placement more effectively.
Autoplaying videos should not exceed 30 seconds in duration.
Click tracking is included in the template.
