Alignment

Use flexbox alignment utilities to vertically and horizontally align columns.

Vertical alignment

Add one of the following classes on .row: align-items-start, align-items-center or align-items-end

One of three columns

Horizontal alignment

Add one of the following classes on .row: justify-content-start, justify-content-center, justify-content-end, justify-content-around or justify-content-between

One of two columns

No gutters

The gutters between columns in our predefined grid classes can be removed with .no-gutters. This removes the negative margins from .row and the horizontal padding from all immediate children columns.

Need an edge-to-edge design? Drop the parent .container or .container-fluid.

.col-12 .col-sm-6 .col-md-8

.col-6 .col-md-4

Column wrapping

If more than 12 columns are placed within a single row, each group of extra columns will, as one unit, wrap onto a new line.

.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.

Column breaks

Breaking columns to a new line in flexbox requires a small hack: add an element with width: 100% wherever you want to wrap your columns to a new line. Normally this is accomplished with multiple .rows, but not every implementation method can account for this.

.col-6 .col-sm-3
