Overlay Expansion

Overlay is an expansion type that overlays or covers up adjacent content.  This type of expansion is supported in the 728×90 ad unit when placed above the header or in the 300×250 ad unit.
Required clickable actions or hit areas for overlays independent of size:
1. Clickthrough (expanded and retracted states)
2. Close button (expanded state only)
3. Rollover to expand (retracted)

300×250

Expansion direction: Can only expand down or left from column 3; down or right from column 1
Max dimensions: 300×600 if expansion is vertical; 600×250 if expansion is horizontal
Special instructions: A column placement must be selected based on expansion direction; downward expansion is not allowed on home, weather or video pages; z-index should be set very high so the overlay appears on top of content

728×90

Expansion direction: Can only expand down
Max dimension: 728×270
Special instructions: Must only be trafficked to top placement of 728×90 above the header and as a result, this ad unit is not supported on the home page; z-index should be set very high so the overlay appears on top of content

Push-Down Expansion

Push-down is an expansion type that pushes all content below it downward. This type of expansion is only supported in the 300×250 ad unit in column 3.  It is not supported in the 728×90 ad unit.

Max dimension: 300×600
Required clickable actions for push-downs:
1. Clickthrough (expanded and retracted states)
