In mid-2017 eBay will begin to turn off active content.
Make sure your item looks good with active content turned off by previewing it now. (This will not impact how others see your listings)

Overview
As described in the 2016 Spring Seller Update, the use of active content in listings, including JavaScript, Flash, plug-ins and form actions, inhibits purchases on mobile devices and can lead to abuse in the marketplace.
- Beginning with the 2017 Spring Seller Update, eBay will limit the use of active content in all new listings across all devices and it will not be rendered by default.
- By the 2017 Fall Seller Update, we plan to remove or block new and existing listings (e.g., GTC listings) and eBay Store pages with active content.
To prepare for these changes, we encourage you to limit or eliminate your use of active content in eBay listings and Stores as soon as possible.
We will provide more information in the 2016 Fall Seller Update about when each type of functionality will be limited or blocked, and provide the specific timing by early 2017. We also are working closely with our third-party partners in cases where they use active content on your item descriptions or stores.
Active content preview feature
Later in April, eBay will provide a feature that allows a seller to toggle between previewing their listing with and without active content enabled in their listing description. This will allow sellers to see the difference between the two (active vs. no active content) and will hopefully assist the seller in optimizing the listing across all devices. The screen shot below demonstrates this new feature/check box.
