All webpages at their core are built on a 12-column grid that spans across the full-width of the page.
Much like the front page of a newspaper, the use of the grid allows for multiple types of content to be displayed on a page within a structure that supports the hierarchy of content, readability, uniformity in spacing, and organization of content.
Within the structure of the 12-column grid, the webpage can be divided up into containers of various sizes that are used to present the required content for the page. The available containers are all based on dividing up our 12-columns across the page.
Fullwidth Container
Fullwidth Container: this container spans the full-width of the 12-columns available.
