Different scroll dynamics within two columns

Hi there,

I created 2 columns with different numbers of items in there. Now I`d like to animate these columns in the way that they have two different speed levels while vertival scrolling. Means the left column should be slower while the right column is a bit faster. Maybe twice faster than the left one. So first question: Is it correct doing it with the element “columns” or better with a grid? And secondly: How do I create this interaction then?

Thanks a lot for your help!

Best,
Frank
