Issues 3 Overlapping styles between different column layouts

## What's Change?
Requires a change to HTML mock up when setting up data-columns attribute. Now each column number is in the form of [total columns number]-[column number] (eg. 2-1, 2-2).

## How To Test
Take a look at the example for column-policy page. It now has six items in it and should go from a 3 column to 2 column grid layout when sizing the browser down.
