I showed this effect earlier – but it is definitely worth looking at again. Here I have applied a gradient fill to the two key elements of the text box. The great thing is that gradient fills can also be applied to select text within one text box.
For design purposes on this one, I reversed the gradient so the top text goes from dark-to-light and the bottom text is the reflection of the gradient going from light-to-dark. And again, all of this remains editable text too. There is a lot of design potential with this feature!
