This demo represents a similar layout to a project I was the lead on while working for the State of Georgia, see below.
If you resize your browser you will see it stretches to fit different sizes automatically.
You can also drag and drop sections, and resize each widget individually.

Uses Gridster (dsmorse.github.io/gridster) to display data in containers/widgets, which can be dragged and dropped dynamically, along with the ability to add/remove elements from the grid. Within each container/widget (using iFrames) is a database connection that displays data based upon dropdown choices. Each widget contains a report viewer, and widgets (up to 12) can be moved around and positioned freely, with or without data inside them due to the Angular setup.
