Technical specification of ad formats

3D MegaBoard (Leader)

Thanks to a great position just above the content the Leader is the first banner to be seen on the page. Together with 3D effect, when the Leader is rotating different slides, it is a nice visual experience for the user and it is hard to be overseen. It can be combined with a branding background as well.




When using the basic animation of the advertising format, it is sufficient to supply static images (JPG, PNG) separately, the banner will be completed on our side.

In the case of extended animations or the use of dynamic elements, it is necessary to supply materials for individual parts created in HTML as separate ZIP archives. The banner will be completed on our side.

Do you need MegaBoard with Branding background?

In that case, add Branding according to specifications

Branding is placed horizontally in the middle of the page. There is a gap of 17 px between the top edge of the page and the top edge of the megaboard. There is a gap of 12 px between the bottom edge of the megaboard and the content of the page.

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.
