The grid is inside a div with class = "container". Within the container, we have rows; within each row we have columns. Bootstrap uses a 12 column grid system. The widths are evenly divided by default, so that if we have 3 columns, each will be 4 wide. There are lots of ways to specify the width of a column, but the most common is to use the col-# classes, where # is the number of columns you want the column to span.
