Notion of offset at time it is useful to give a certain offset in terms of number of columns which moves the column to the right of a certain number of columns. This is a typical html markup for a grid with three columns. This way all the content in your columns is visually aligned down the left side.

Each column has some horizontal padding called a gutter for controlling the space between them. Rows are wrappers for columns. The usual gutter size is 30px which says that each column leaves a horizontal space of 15px gutter 2 between each other. Grid columns are created by specifying the number of 12 available columns you wish to span.
