How to Add a Side Banner

Unbounce does not include a sticky side banner element, but you can pin a Box element to the side of the viewport with custom CSS so it stays in place as the visitor scrolls.

This uses custom CSS and is not an official Unbounce feature. Consider whether a fixed side element suits your page; on many landing pages a single, focused call to action converts better than added sidebar content.

Pin a Box element to the side

Add a Box element to your page, then add a stylesheet targeting that box's ID. Replace the ID with your own:

<style>
  #lp-pom-box-123 {
    position: fixed;
    top: 0;
    left: 20px;
    width: 320px;
    height: 100%;
  }
</style>

To find the box's ID, publish the page and inspect the element in your browser's developer tools; it follows the pattern lp-pom-box- with a number. Adjust left or right, width, and top to position the banner.
