Make dynamic fixed to scrollable element

[meedup]

Is it possible to make an element that is fixed only until a certain height during scrolling?

Also, is it possible to make a color-changing/revealing element during scrolling?

Mainly what I am looking for is reproducing this effect:

From the title "a new vision" that is white, stays fixed, you roll it off the image it turns black then starts rolling alongside the page.

Couldn't find anything this specific in the tutorials.

Nice effect. Inspecting the element (a new vision) shows that the text is using a clipping path and maybe a scroll sprite? Would be great if one of the Xd gurus can save a lot of trial and error on trying to create this effect.
