This is a wide format unit with a "Close Ad X" button. When the button is clicked, the ad disappears, page content is pushed up, and a "Show ad" button is displayed. When "Show ad" is clicked, the ad reappears and the page content is pushed back down.
Place your brand content front-and-center using this highly visible ad format, while still giving the user an option to hide the ad.
