Angled Div sections using 2D rotate spanning the entire page

So I’m trying to create a three-slide header with each slide at a slight angle. I want it to span the width of the frame and have an animated opening on each slide. The question is how to angle the sections equally and make sure it fills the screen width without the white background. If I need to rethink my approach to something like a clipping mask then I’m open to it.
