Grid options

While Bootstrap uses `em`s or `rem`s for defining most sizes, `px`s are used for grid breakpoints and container widths. This is because the viewport width is in pixels and does not change with the font size. See how aspects of the Bootstrap grid system work across multiple devices with a handy table.

	Extra small <576px	Small ≥576px	Medium ≥768px	Large ≥992px	Extra large ≥1200px
Max container width	None (auto)	540px	720px	960px	1140px
Class prefix	`.col-`	`.col-sm-`	`.col-md-`	`.col-lg-`	`.col-xl-`
# of columns	12
Gutter width	30px (15px on each side of a column)
Nestable	Yes
Column ordering	Yes

Grid Example

Using a single set of `.col-md-*` grid classes, you can create a basic grid system that starts out stacked on mobile devices and tablet devices (the extra small to small range) before becoming horizontal on desktop (medium) devices. Place grid columns within any `.row`.

.col-sm-1

.col-sm-2

.col-sm-3

.col-sm-4

.col-sm-6

.col-sm-12

Variable width content

Use `col-{breakpoint}-auto` classes to size columns based on the natural width of their content.

Reordering

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 `12` across all five grid tiers.

First, but unordered

Second, but last

Third, but first

There are also responsive `.order-first` and `.order-last` classes that change the `order` of an element by applying `order: -1` and `order: 13` (`order: $columns + 1`), respectively. These classes can also be intermixed with the numbered `.order-*` classes as needed.

Offsetting columns

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.

.col-md-4

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

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

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

Nesting

To nest your content with the default grid, add a new `.row` and set of `.col-sm-` columns within an existing `.col-sm-` column. Nested rows should include a set of columns that add up to 12 or fewer (it is not required that you use all 12 available columns).

Level 1: .col-sm-9

Level 2: .col-8 .col-sm-6

Level 2: .col-4 .col-sm-6

Horizontal alignment

Use flexbox alignment utilities to vertically and horizontally align columns.
