Design requirements

Do you want animation or video in the branding header?

KFor this purpose, it is necessary to supply the MegaBoard banner. If you don't want any animations in the branding header, don't add Megaboard! For animations within the entire branding area, you can use HTML5 format.

Are you tasked with preparing Crossplatform Branding (desktop + mobile)?

In this case, it is necessary to supply documents for the mobile version of branding. Specifications for its production can be found here: Specifications for the production of mobile branding.

For the smooth start and running of campaigns, the documents which do not meet described specification must be aprooved by the MAFRA technical department in advance. Thank you for your understanding.
