Column wrapping
.col-9
.col-4
Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.
.col-6
Subsequent columns continue along the new line.
Margin utilities

With the move to flexbox in v4, you can use margin utilities like .me-autoto force sibling columns away from one another.

.col-md-4
.col-md-4 .ms-auto
.col-md-3 .ms-md-auto
.col-md-3 .ms-md-auto
.col-auto .me-auto

Order classes
First in DOM, no order applied
Second in DOM, with a larger order
Third in DOM, with an order of 1

There are also responsive .order-first and .order-last classes that change the order of an element by applying order: -1 and order: 6, respectively. These classes can also be intermixed with the numbered .order-* classes as needed.

First in DOM, ordered last
Second in DOM, unordered
Third in DOM, ordered first
Standalone column classes

The .col-* classes can also be used outside a .row to give an element a specific width. Whenever column classes are used as non direct children of a row, the paddings are omitted.

.col-3: width of 25%
.col-sm-9: width of 75% above sm breakpoint
