Use our powerful mobile-first flexbox grid to build layouts of all
shapes and sizes thanks to a twelve column system, five default
responsive tiers, Sass variables and mixins, and dozens of
predefined classes, properties and components.
How it works
Reactstrap and Bootstrap’s grid system uses a series of containers
(Container), rows (Row), and columns (Col) to layout and align content. It’s built with
flexbox
and is fully responsive. Below is an example and an in-depth look at
how the grid comes together.
The above example creates three equal-width columns on small,
medium, large, and extra large devices using our predefined grid
classes. Those columns are centered in the page with the parent
Container.
Grid options
While Bootstrap uses
ems or
rems for
defining most sizes,
pxs 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.

Auto-layout columns
Utilize breakpoint-specific column classes for easy column sizing
without an explicit breakpoint prop like
sm="6".
Equal-width
For example, here are two grid layouts that apply to every device
and viewport, from
xs to
xl. Add
any number of unit-less classes for each breakpoint you need and
every column will be the same width.
1 of 2
2 of 2
1 of 3
2 of 3
3 of 3
Equal-width columns can be broken into multiple lines, but there was
a
Safari flexbox bug
that prevented this from working without an explicit
flex-basis
or border.
There are workarounds for older browser versions, but they shouldn’t
be necessary if you’re up-to-date.

Setting one column width
Auto-layout for flexbox grid columns also means you can set the
width of one column and have the sibling columns automatically
resize around it. You may use predefined grid classes (as shown
below), grid mixins, or inline widths. Note that the other columns
will resize no matter the width of the center column.

Variable width content
Use
{breakpoint}="auto"
props to size columns based on the natural width of their content.

Equal-width multi-row
Create equal-width columns that span multiple rows by inserting a
.w-100
where you want the columns to break to a new line. Make the breaks
responsive by mixing the
.w-100
with some responsive display utilities.

Responsive props
Reactstrap’s grid includes five tiers of predefined props for
building complex responsive layouts. Customize the size of your
columns on extra small, small, medium, large, or extra large devices
however you see fit.
Bootstrap breakpoints
For grids that are the same from the smallest of devices to the
largest, use the
Col and
Col xs=*
tags and props. Specify a numbered
xs prop
when you need a particularly sized column; otherwise, feel free to
stick to blank
Col tag.

Stacked to horizontal
Using a single set of
.col-sm-*
classes, you can create a basic grid system that starts out stacked
and becomes horizontal at the small breakpoint (sm).
sm="8"
sm="4"

Mix and match
Don’t want your columns to simply stack in some grid tiers? Use a
combination of different classes for each tier as needed. See the
example below for a better idea of how it all works.
xs="12" md="8"
xs="6" md="4"
xs="6" md="4"
xs="6" md="4"
xs="6" md="4"
xs="6"
xs="6"
Reactstrap Layout
For faster mobile-friendly and responsive development, Bootstrap
includes dozens of utility classes for showing, hiding, aligning,
and spacing content.
Reactstrap Container
Containers are the most basic layout element in Reactstrap
(Bootstrap) and are required when using our default grid system.
Containers are used to contain, pad, and (sometimes) center the
content within them. While Containers can be nested, most layouts do
not require a nested Container.
Reactstrap (Bootstrap) comes with three different containers:
<Container>, which sets a max-width at each responsive breakpoint
<Container fluid>, which is width: 100% at all breakpoints
<Container fluid={breakpoint}>, which is width: 100% until the specified breakpoint
