It obviously does work, thanks very much.
I was trying to do it myself yesterday, playing with Developer Tools and inspecting classes and IDs of each div element involved there. I even came up with the .rev_slider_wrapper class property, but alone. I omitted the .features-list-alternate one. If I would look at the beggining of my own post, it would be apparent there.
May I ask for a short explanation why both classes need to be called on the line and how can I find this out myself in the Developer Tools in order to save your valuable time?
