Well first you must continue to understand the Grid before you can even fathom breaking it! Don’t forget that grids do not make the design or its final look. It only dictates clarity to the reader, efficiency and continuity. You should never make your grid too obvious. It should be the layout structure without being the center of attention and taking away from the text and images. After all the grid is used to help a reader through the layout, not notice it. Not only that but, the grid allows for you to layout massive amount of design and text since margins, and horizontal and vertical spacing have already been predetermined. There are several parts of the grid. Listing from left to right.

-Columns
They are vertical spaces that hold type and images. The width and number of columns per page can vary depending on the information.

Modules
They are the individual divisions separated by consistent space. They are repeating ordered boxes on the grid. Combining them creates columns and rows.

Margins
They represent the amount of space between the trim size (including the gutter) and the layout. Margins can also be used to provide secondary information (such as notes, captions, dates, design (mostly bleeds), etc.).

Flow-lines
They are the alignments that break the columns into horizontal rows. They are a method for using space and design elements to guide readers across the layout.

Spatial Zones
They are the groups of modules or columns that form areas that are just for type, ads, images, and other information.

Markers
They are there to help a reader navigate through the pages. It Indicates placement for material that appears in the same location. Usually they include include page numbers, running headers and footers, and icons.
