Technical specification of ad formats

Branding AdTabs

Branding AdTabs is based on Branding format, which is due to its size around entire page excellently visible for all the time a user is scrolling down the page. In this case, however, it is supplemented by a branding icon located on the side that will expand when you click to reveal additional content in the form of pictures or videos.

Design requirements

  1. The branding must not be transparent
  2. Place important advertising messages in a 1366 × 768 px wide column (see red area in drawing.) This is very important due to the different resolutions and ratios of the display devices. This area is visible to most users.
