Problem/Motivation
The annotation for the Umami demo's grid-2.css file reads as "This file is used to create a 3 column grid layout.", but the filename and CSS properties would seem to indicate styling for a 2 column grid, instead.
Proposed resolution
Change "This file is used to create a 3 column grid layout." to "This file is used to create a 3 column grid layout." instead.
Remaining tasks
Change the annotation.
