I know it's a topic that has been answered several times, but I'm playing with css "background-attachment:fixed" property, and I wanted to make it work on mobile devices.
The answer is: it's not possible, because it is forced to "scroll" for performence reasons. Knowing that, I still tried, and I found these examples on w3schools : example 1, example 2.
These two examples both work on my chrome mobile browser (running on Android 7.0). No matter how hard I try, I can't reproduce this behaviour.
I inspected the code and it seems based solely on background-attachment to work.
How is it possible, and how can I reproduce this?
