How to make angular div using html & css : I am using html, css, and bootstrap.

I have 2 horizontal divs:

    <div class="container-fluid">
      ...div content...
    </div>

    <div class="container-fluid">
      ...div content...
    </div>

They each have a background image, and I would like them to meet up in a triangular manner like [this site](http://www.solarcity.com)
