Live previews are a working sample of your finished product, and your opportunity to showcase the features and structure unique to your item. We recommend creating live previews for themes or templates so that potential customers can get a closer look at your items, and help avoid any confusion.
There are a few important things to be aware of when creating your live previews.
We serve live previews through an iframe on preview.themeforest.net and preview.codecanyon.net, but browser security and privacy features may mean that the way your previews function within the iframe could be affected.
Another reason why your live preview may appear different to customers is because functionality (including defaults) can differ quite a lot between different browsers, and users can change their privacy settings easily.
Due to these reasons, the way customers see and interact with your preview may be affected.
To help get a better understanding of how your live previews may be impacted, we recommend opening them up (across different browsers) within the developer tools to view any errors or warnings that come up.
