I did consider the iframe option, but the site is responsive and I was unsure about how to resizing an iframe based on it’s respective content size. There’s also the problem of a big blank square on the page if the edge animation doesn’t load, which is still occasionally an issue – not sure why. Adding the animation manually and ensuring that the js file was enqueued solved the problem. Not sure what Edge Suite does differently as it’s outside my depth.
Thanks for the reply, all the same.
