Yes. We offer three options for styling your widget: Responsive, Fixed, and Custom. Most publishers find that the responsive widgets generate the best performance. These widget styles are designed to fill the width they are placed into. If your site is responsive, the widget will adjust accordingly as the browser is resized.
NOTE: Please do not hide any of the widget’s content based on browser width or other factors. This will invalidate your reporting data and hurt the widget’s ability to optimize to the best performing content. If you wish to show a different number of ads on mobile, we suggest creating separate widgets for each device.
