Grid options

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

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
Container width None (auto) 750px 970px 1170px
Class prefix .col-xs- .col-sm- .col-md- .col-lg-
# of columns 12
Column width Auto ~62px ~81px ~97px
Gutter width 30px (15px on each side of a column)
Nestable Yes
Offsets Yes
Column ordering 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. Place grid columns in any .row.

Example: Fluid container

Turn any fixed-width grid layout into a full-width layout by changing your outermost .container to .container-fluid.

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, desktop

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

Example: 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-xs-9
.col-xs-4
Since 9 + 4 = 13 > 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.
.col-xs-6
Subsequent columns continue along the new line.

Responsive column resets

With the four tiers of grids available you're bound to run into issues where, at certain breakpoints, your columns don't clear quite right as one is taller than the other. To fix that, use a combination of a .clearfix and our responsive utility classes.

.col-xs-6 .col-sm-3
.col-xs-6 .col-sm-3
.col-xs-6 .col-sm-3
.col-xs-6 .col-sm-3

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.

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-xs-* Visible
.visible-sm-* Visible
.visible-md-* Visible
.visible-lg-* Visible
.hidden-xs Visible Visible Visible
.hidden-sm Visible Visible Visible
.hidden-md Visible Visible Visible
.hidden-lg Visible Visible Visible

As of v3.2.0, the .visible-*-* classes for each breakpoint come in three variations, one for each CSS display property value listed below.

Group of classes CSS display
.visible-*-block display: block;
.visible-*-inline display: inline;
.visible-*-inline-block display: inline-block;

So, for extra small (xs) screens for example, the available .visible-*-* classes are: .visible-xs-block, .visible-xs-inline, and .visible-xs-inline-block.

The classes .visible-xs, .visible-sm, .visible-md, and .visible-lg also exist, but are deprecated as of v3.2.0. They are approximately equivalent to .visible-*-block, except with additional special cases for toggling <table>-related elements.

Print classes

Similar to the regular responsive classes, use these for toggling content for print.

Classes Browser Print
.visible-print-block
.visible-print-inline
.visible-print-inline-block 		Visible
.hidden-print Visible

The class .visible-print also exists but is deprecated as of v3.2.0. It is approximately equivalent to .visible-print-block, except with additional special cases for <table>-related elements.

Test cases Visible on...

Resize your browser or load on different devices to test the responsive utility classes.

Green checkmarks indicate the element is visible in your current viewport.

✔ Visible on x-small
✔ Visible on small
Medium ✔ Visible on medium
✔ Visible on large
✔ Visible on x-small and small
✔ Visible on medium and large
✔ Visible on x-small and medium
✔ Visible on small and large
✔ Visible on x-small and large
✔ Visible on small and medium

Test cases Hidden on...

Here, green checkmarks also indicate the element is hidden in your current viewport.

✔ Hidden on x-small
✔ Hidden on small
Medium ✔ Hidden on medium
✔ Hidden on large
✔ Hidden on x-small and small
✔ Hidden on medium and large
✔ Hidden on x-small and medium
