Columns
Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.
Subsequent columns continue along the new line.
With the move to flexbox in v4, you can use margin utilities like .me-autoto force sibling columns away from one another.
You may also apply this break at specific breakpoints with our responsive display utilities.
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.
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.
