If you go to http://www.mbie.govt.nz/, you will see some rows that are divided into 3 columns. One of the rows has 3 pictures. For the sake of having clear communication, let’s say that each row is divided into 3 cells.
Each cell has a heading, information about the heading and a link to even more information.
Please tell me where to go in your knowledge base to learn how to set up rows & cells.
