It is basically a text version (As opposed to an image version) of Before and After Slider - so I think you guys already have 95% of the work done. The idea is to be able to format the text and background https://apps.elfsight.com/panel/applications/before-and-after-slider/add/

Business case here is text is just as important as images for this kind of slider (when people tell their story). I could use images with text on them but this takes way too long to create, format etc as I look to scale. (And Elfsight is about making things easier, better and faster)
