The Grid Method
Imagine laying out a grid across your content area. You do not have to determine the amount of rows as these are dynamically built. You need to indicate that you would like content in a grid first using the tag below:
This will will also need a closing tag.
This creates the rows. Next you add your columns by inserting the [box] short code. This too will have to be closed, but your content and/or images go between them. See the example below
[box]This is my first column[/box]
[box]This is my second column[/box]
[box]This is my third column[/box]
Depending on your page/post layout you will get either 2, 3 or 4 across before the grid forms another row.
