Adhesion Expanded for Smartphone & Tablets

[Richard Smith]

Behavior and UI Elements with Implementation Notes

Adhesion keeps the same size and resolution no matter how the publisher
content is adjusted by zooming or scrolling.
Aside from the general aspect ratio of the ad unit, specific sizes
depend on the size of the device screen, therefore developing a
responsive design to accommodate wider smartphones or thinner
tablet sizes are recommended
The size of the adhesion banner may be made wider when the orientation of the device changes, but image graphics of the ad should not be stretched to accommodate the width
