Yandex.Direct adaptive unit
Creating new Yandex.Direct blocks is currently not supported. Use strategies to create RTB blocks and manage displays of contextual and banner ads.
The adaptive unit adapts to the dimensions of the container and is suitable for sites with an adaptive layout. If the layout specifies the width and height of the container for inserting the ad unit, then the adaptive unit will be sized according to these dimensions. If the container dimensions have not been specified or you are unable to define them, then you can use the dimensions that are specified in the code editor.
The minimum width of the unit is 160 pixels, and the maximum height is 90 pixels. Note that the area that is required to display one Yandex.Direct ad is 60,000 square pixels (for example, 200 × 300 pixels).
The maximum number of ads in the unit is 9 ads in Yandex.Direct.
