I'm using the District theme and GemPages was also used. I'm trying to add code to make it fade in on scroll, like this example - http://jsfiddle.net/mohammadAdil/DFeqH/. I'm having trouble actually applying that example to my code. I also found other examples but I'm not sure where to put the code.
Actually, it needs to advance in customizing code due to the difference of HTML Dom Structure, so could you please share with me your collection page URL and another example that you found, then I can understand more detail your wishing.
Thank you so much!
Sorry for the late reply. Our tech staff needs to check and try to do some custom codes, so it takes time to solve this. This is a demo from us, please help me check it and let me know if it is good:
