# Grid options

See how aspects of the Bootstrap grid system work across multiple devices with a handy table.

### BuiltWith Bootstrap

Bootstrap is made to not only look and behave great in the latest desktop browsers, but in tablet and smartphone browsers too. It’s packed with great features. Such as the 12-column responsive mobile first grid, dozens of components, plugins and more!

| Extra small devices Phones (<768px) | Small devices Tablets (≥768px) | Medium devices Desktops (≥992px) | Large devices Desktops (≥1200px)
--- | --- | --- | --- | ---
Grid behavior | Horizontal at all times | Collapsed to start, horizontal above breakpoints
Max container width | None (auto) | 750px | 970px | 1170px
Class prefix | `.col-xs-` | `.col-sm-` | `.col-md-` | `.col-lg-`
# of columns | 12
Max column width | Auto | 60px | 78px | 95px
Gutter width | 30px (15px on each side of a column)
Nestable | Yes
Offsets | N/A | Yes
Column ordering | N/A | Yes

###### Example: Stacked-to-horizontal

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.

.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-1
.col-md-8
.col-md-4
.col-md-4
.col-md-4
.col-md-4
.col-md-6
.col-md-6

###### Example: Mobile and desktop

Don't want your columns to simply stack in smaller devices? Use the extra small and medium device grid classes by adding `.col-xs-*` `.col-md-*` to your columns. See the example below for a better idea of how it all works.

.col-xs-12 col-md-8
.col-xs-6 .col-md-4
.col-xs-6 .col-md-4
.col-xs-6 .col-md-4
.col-xs-6 .col-md-4
.col-xs-6
.col-xs-6

###### Example: Mobile, tablet, desktops

Build on the previous example by creating even more dynamic and powerful layouts with tablet `.col-sm-*` classes.

.col-xs-12 .col-sm-6 .col-md-8
.col-xs-6 .col-sm-6 .col-md-4
.col-xs-6 .col-sm-4 .col-md-4
.col-xs-6 .col-sm-4 .col-md-4
.col-xs-6 .col-sm-4 .col-md-4

###### Offsetting columns

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

.col-md-4
.col-md-4 .col-md-offset-4
.col-md-3 .col-md-offset-3
.col-md-3 .col-md-offset-3
.col-md-6 .col-md-offset-3

###### Nesting columns

To nest your content with the default grid, add a new `.row` and set of `.col-md-*` columns within an existing `.col-md-*` column. Nested rows should include a set of columns that add up to 12.

Level 1: .col-md-12
Level 2: .col-md-6
Level 2: .col-md-6

# Responsive utilities

For faster mobile-friendly development, use these utility classes for showing and hiding content by device via media query. Also included are utility classes for toggling content when printed.

Try to use these on a limited basis and avoid creating entirely different versions of the same site. Instead, use them to complement each device's presentation. Responsive utilities are currently only available for block and table toggling. Use with inline and table elements is currently not supported.

### Available classes

Use a single or combination of the available classes for toggling content across viewport breakpoints.

| Extra small devices Phones (<768px) | Small devices Tablets (≥768px) | Medium devices Desktops (≥992px) | Large devices Desktops (≥1200px)

`.visible-sm` | Hidden | Visible | Hidden | Hidden
`.visible-md` | Hidden | Hidden | Visible | Hidden

`.hidden-xs` | Hidden | Visible | Visible | Visible
`.hidden-sm` | Visible | Hidden | Visible | Visible
