The OptimizePress Live Editor is awesome but you might need to make a column float a different direction when the site is scaled down to a mobile device.
A good use case is you have an opt-in form on the left, and your offer description on the right. With mobile responsive design, the right columns always fall under the left columns. So in a 2 column row, the right column would end up under the left column. Not always ideal.
Use the code below to change how the columns adapt to mobile devices by changing the direction of how they stack on mobile device.
