How would I make the text disappear when it gets to end of the page please?

I would like it scroll then get to the bottom where the footer is the full width of the page, but not necessarily the full height.

This* is a good indication of what I want, but with a subscribe footer instead. I don’t know how to make the text disappear and I’ve exhausted all options so many tips are appreciated !!
