Shift Col

The columns on the left side in a row are always above those on the right on mobile. However, you can rearange columns position in Act2 so they appear inverted on desktop, but still stack naturally on mobile.

You can achieve this by adding the shift-col class to the columns direct parent group. Please keep in mind this only works with two columns, not three or more:
