Technical specification of ad formats

3D Rectangle (480x300)

Thanks to its location, WideSquare is a very distinctive and popular ad format. Can’t be overlooked either on the home page or in the article. Together with 3D effect, when the banner rotates and alternates different slides, it is more attractive for a user and nearly impossible to overlook it.




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.
