All expandables must be user-initiated across the site. CNN.com strongly recommends and prefers 'click to initiate', however, will accept roll over/roll off pending site approval.

Method of expansion and un-expansion must be the same. (i.e., click-to-initiate or click-to-close OR rollover-to-initiate or roll off-to-close)

Site pre-approval is required before accepting an expandable banner on the Home page. If approved for the Home page, user initiation must be click-to-initiate and click-to-close. Preferred execution includes 300x250 expansion LEFT to 500x250 ONLY.

Additionally, CNN.com must pre-approve expandables for section fronts. Preferred execution includes 336x280 expansion DOWN to 336x500 OR LEFT to 500x280. Click to expand is preferred however 'roll on/roll off' will be accepted pending site approval.
