{{< callout info >}} Heads up! Be sure to [read the Grid page]({{< docsref "/layout/grid" >}}) first before diving into how to modify and customize your grid columns. {{< /callout >}}

How they work

• Columns build on the grid's flexbox architecture. Flexbox means we have options for changing individual columns and [modifying groups of columns at the row level]({{< docsref "/layout/grid#row-columns" >}}). You choose how columns grow, shrink, or otherwise change.

• When building grid layouts, all content goes in columns. The hierarchy of Bootstrap's grid goes from [container]({{< docsref "/layout/containers" >}}) to row to column to your content. On rare ocassions, you may combine content and column, but be aware there can be unintended consequences.

• Bootstrap includes predefined classes for creating fast, responsive layouts. With [six breakpoints]({{< docsref "/layout/breakpoints" >}}) and a dozen columns at each grid tier, we have dozens of classes already built for you to create your desired layouts. This can be disabled via Sass if you wish.

Alignment

Use flexbox alignment utilities to vertically and horizontally align columns.

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.

{{< example class="bd-example-row" >}}

.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.

{{< /example >}}

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.

{{< example class="bd-example-row" >}}

.col-6 .col-sm-3

.col-6 .col-sm-3

<!-- Force next columns to break to new line -->
<div class="w-100"></div>

<div class="col-6 col-sm-3">.col-6 .col-sm-3</div>
<div class="col-6 col-sm-3">.col-6 .col-sm-3</div>

{{< /example >}}

You may also apply this break at specific breakpoints with our [responsive display utilities]({{< docsref "/utilities/display" >}}).

{{< example class="bd-example-row" >}}

.col-6 .col-sm-4

.col-6 .col-sm-4

<!-- Force next columns to break to new line at md breakpoint and up -->
<div class="w-100 d-none d-md-block"></div>

<div class="col-6 col-sm-4">.col-6 .col-sm-4</div>
<div class="col-6 col-sm-4">.col-6 .col-sm-4</div>

{{< /example >}}

Reordering

Order classes

Use .order- classes for controlling the visual order of your content. These classes are responsive, so you can set the order by breakpoint (e.g., .order-1.order-md-2). Includes support for 1 through 5 across all six grid tiers.

{{< example class="bd-example-row" >}}

First in DOM, no order applied

Second in DOM, with a larger order

Third in DOM, with an order of 1

{{< /example >}}

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.

{{< example class="bd-example-row" >}}

First in DOM, ordered last

Second in DOM, unordered

Third in DOM, ordered first

{{< /example >}}

Offsetting columns

You can offset grid columns in two ways: our responsive .offset- grid classes and our [margin utilities]({{< docsref "/utilities/spacing" >}}). Grid classes are sized to match columns while margins are more useful for quick layouts where the width of the offset is variable.

Offset classes

Move columns to the right using .offset-md-* classes. These classes increase the left margin of a column by * columns. For example, .offset-md-4 moves .col-md-4 over four columns.

{{< example class="bd-example-row" >}}

.col-md-4

.col-md-4 .offset-md-4

.col-md-3 .offset-md-3

.col-md-3 .offset-md-3

.col-md-6 .offset-md-3

{{< /example >}}

In addition to column clearing at responsive breakpoints, you may need to reset offsets. See this in action in [the grid example]({{< docsref "/examples/grid" >}}).

{{< example class="bd-example-row" >}}

.col-sm-5 .col-md-6

.col-sm-5 .offset-sm-2 .col-md-6 .offset-md-0

.col-sm-6 .col-md-5 .col-lg-6

.col-sm-6 .col-md-5 .offset-md-2 .col-lg-6 .offset-lg-0

{{< /example >}}

Margin utilities

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

{{< example class="bd-example-row" >}}

.col-md-4

.col-md-4 .ml-auto

.col-md-3 .ml-md-auto

.col-md-3 .ml-md-auto

.col-auto .mr-auto

.col-auto

{{< /example >}}

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.

{{< example >}}

.col-3: width of 25%

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

{{< /example >}}

The classes can be used together with utilities to create responsive floated images. Make sure to wrap the content in a [.clearfix]({{< docsref "/helpers/clearfix" >}}) wrapper to clear the float if the text is shorter.

{{< example >}}

{{< placeholder width="100%" height="210" class="col-md-6 float-md-right mb-3 ml-md-3" text="Responsive floated image" >}}
