Usually, these HTML templates have place-holders or tokens to hold the listing specific information. The emphasis of this feature is on enabling you to use the same HTML template for multiple product listings, yet display information that is specific to a product in your eBay store. Most sellers create 1 or more HTML templates for listing their items on eBay. This feature helps sellers to enhance the way their product looks on eBay and to be consistent in terms of branding.
EBay provides its sellers with an option to use HTML templates for listing items, where sellers could provide a rich HTML content template (on an item level) and fully control the appearance of the listing on the eBay front end.
