I am trying to modify my application to be able to open it on smaller screens (ipad). I have modified css to achieve this, but I would also like to change layout when width is smaller than x. I have two dbc.Columns on my page. And based on width I would like to change its position to have one under another. It can be achived be changing width of both cols to 12. Is there any way to do this? I was thinking about implementation of js code, but I haven’t found any solution to trigger callback with it.
