I've gone through the tutorials and I've gone through the API and I can't for the life of me figure out how to change the page background on hover. My background id is page, but in the OnHover function it is telling me that neither .src nor .background are available options. I don't really know Javascript at all, though I'm reasonable at C#. I've looked for tutorials on YouTube and Google and can't find anything. I'm basically trying to recreate this effect (https://www.camposanto.com/). Any ideas?
