Hi, for you first question, there is a way to change the field box to have it inverted or transparent. Select the field widget, go to the widget menu and you should be able to change it there.
As for the fading effect, the only way I know how is to have two identical cards, one with and the other without the text and to add a fading transition between them.
And as for the typewriter effect, there's Millie who did a great module for that. You can find it here. I hope this helps
