Is it possible to fix the unit before the end of the scroll elements in it?

Suppose the site has 2 units.
The first occupies the entire height of the screen. But it is information which is "not fit" and for this you need to fix this unit until will not be scrolled all the information.
How can I do that?

Using css to set parent unit
overflow: hidden;
overflow-y: scroll;
It was easier than I thought)
