JavaScript, CSS: Clip to be inside parent DIV - Stack Overflow

Context

I have a bunch of nested DIVs (implementing a simple window system, for learning purposes, with DIVs).

Problem:

Let divA = child of divB.

Now, ideally, I want the contents of divA to be "clipped" inside of divB.

Thus, if I take divA, and drag it to the right ... as it gets out of the border of divB, I want the parts of divA that are outside of divB to be chopped off and not displayed.

Question:

How do I do this? How do I use one div to clip / mask another div?

Thanks!

.divA {
    overflow: hidden;
}
