How to create a matrix from DOM element?

Question

JavaScript

Hi all gentlemen. I've been struggling with this problem for a few hours now. No idea will come to mind.
I have html + css - https://jsfiddle.net/662aww2e/
I need to create a matrix based on this type:

[
  [div.cell, div.cell, div.cell],
  [div.cell, div.cell, div.cell],
  [div.cell, div.cell, div.cell],
  [div.cell, div.cell, div.cell],
  [div.cell, div.cell, div.cell],
]

Is it possible to do so?
