Microsoft Responsive Header


The MSN Responsive Header* Ad takes advantage of the responsive design of MSN.  An Advertiser can choose to display a single creative across all three page widths (2-, 3-, 4-column views), or can customize the creative for each of the page widths.  The creative can re-animate on page resize, if desired.  The user can collapse the ad to a smaller branded experience and then reopen it later, similar to the Billboard.
