How do you make text fade?

Several of the websites I frequent display text that gradually gets dimmer and dimmer until you can’t read it any more. The goal is to get you interested in a story that resides behind a paywall. If you want to read more have to join the club to log in.

This example from the Wall Street Journal shows what I mean:
https://www.wsj.com/articles/the-worst-of-the-global-selloff-isnt-here-yet-banks-and-investors-warn-11584877018?mod=hp_lead_pos2

Is there a stack somewhere that produces this fading text?

What kind of stack would you use to link the text to some kind of pay wall?

Ooops disregard my original post if you read it. I mistook how you wanted the text to fade. If you want a timed fade where the whole text block disappears then a stack like joe workman’s impact would be good. There are stacks to fade the text with a gradient fade as in your example. Can’t recall them off top of my head. A google should yield some.

Paragraph Pro from Big White Duck will do this I believe.
