Columns can be easily changed by using the .col-md-push-* and .col-md-pull-* classes (column) order.

Copy after login

Look at the running rendering:

As you can see, I have defined three lines.

The first row is divided equally into 4 parts, each occupies 3 columns. This line is mainly for comparison with the following two lines.

There is only one element in the second row and it occupies 3 columns, and then the .col-md-push-3 style class is also added to this element. (Let the element occupying 3 columns be moved 3 columns to the right, so it now occupies 3 columns: 4, 5, and 6.)

The third column is divided into two parts, the first part It occupies 9 columns (use col-md-push-3 to move 3 columns to the right), and the second copy occupies 3 columns (use col-md-pull-9 to move 9 columns to the left).
