Grid system

Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.

Introduction

Grid systems are used for creating page layouts through a series of rows and columns that house your content. Here's how the Bootstrap grid system works:

  • Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
  • Use rows to create horizontal groups of columns.
  • Content should be placed within columns, and only columns may be immediate children of rows.
  • Predefined grid classes like .row and .col-xs-4 are available for quickly making grid layouts. Less mixins can also be used for more semantic layouts.
  • Columns create gutters (gaps between column content) via padding. That padding is offset in rows for the first and last column via negative margin on .rows.
  • Grid columns are created by specifying the number of twelve available columns you wish to span. For example, three equal columns would use three .col-xs-4.

html of columns 12
Column width Auto 60px 78px 95px
Gutter width 30px (15px on each side of a column)
Nestable Yes
Offsets Yes
Column ordering Yes

Grid classes apply to devices with screen widths greater than or equal to the breakpoint sizes, and override grid classes targeted at smaller devices. Therefore, applying any .col-md- class to an element will not only affect its styling on medium devices but also on large devices if a .col-lg- class is not present.

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.


{html:div class=container-fluid}
  {html:row}
  {/html:row}
{/html:div}

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

{html:row}
 {html:col class="col-xs-12 col-md-8"}
  .col-xs-12 .col-md-8
{/html:col} {html:col class="col-xs-6 col-md-4"} .col-xs-6 .col-md-4
{/html:col} {/html:row} {html:row} {html:col class="col-xs-6 col-md-4"} .col-xs-6 .col-md-4
{/html:col} {html:col class="col-xs-6 col-md-4"} .col-xs-6 .col-md-4
{/html:col} {html:col class="col-xs-6 col-md-4"} .col-xs-6 .col-md-4
{/html:col} {/html:row} {html:row} {html:col class="col-xs-6"} .col-xs-6
{/html:col} {html:col class="col-xs-6"} .col-xs-6
{/html:col} {/html:row}

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

{html:row}
 {html:col class="col-xs-12 col-sm-6 col-md-8"}
  .col-xs-12 .col-sm-6 .col-md-8
{/html:col} {html:col class="col-xs-6 col-md-4"} .col-xs-6 .col-md-4
{/html:col} {/html:row} {html:row} {html:col class="col-xs-6 col-sm-4"} .col-xs-6 .col-sm-4
{/html:col} {html:col class="col-xs-6 col-sm-4"} .col-xs-6 .col-sm-4
{/html:col} {html:col class="col-xs-6 col-sm-4"} .col-xs-6 .col-sm-4
{/html:col} {/html:row}

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

{html:row}
 {html:col class="col-xs-6 col-sm-3 "}
  .col-xs-6 .col-sm-3
{/html:col} {html:col class="col-xs-6 col-sm-4"} .col-xs-6 col-sm-3
{/html:col} {html:div class=clearfix visible-xs}{/html:div} {html:col class="col-xs-6 col-sm-3 "} .col-xs-6 .col-sm-3
{/html:col} {html:col class="col-xs-6 col-sm-4"} .col-xs-6 col-sm-3
{/html:col} {/html:row}

In addition to column clearing at responsive breakpoints, you may need to reset offsets, pushes, or pulls

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

{html:row}
 {html:col class="col-sm-5 col-md-6"}
  .col-sm-5 .col-md-6
{/html:col} {html:col class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0"} .col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0
{/html:col} {/html:row}{html:row} {html:col class="col-sm-6 col-md-5 col-lg-6"} .col-sm-6 .col-md-5 .col-lg-6
{/html:col} {html:col class="col-sm-6 col-md-5 col-md-offset-2 col-lg-6 col-lg-offset-0"} .col-sm-6 .col-md-5 .col-md-offset-2 .col-lg-6 .col-lg-offset-0
{/html:col} {/html:row}

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

{html:row}
 {html:col class="col-md-4"}
  .col-md-4
{/html:col} {html:col class="col-md-4 col-md-offset-4"} .col-md-4 .col-md-offset-4
{/html:col} {/html:row} {html:row} {html:col class="col-md-3 col-md-offset-3"} .col-md-3 .col-md-offset-3
{/html:col} {html:col class="col-md-3 col-md-offset-3"} .col-md-3 .col-md-offset-3
{/html:col} {/html:row} {html:row} {html:col class="col-md-6 col-md-offset-3"} .col-md-6 .col-md-offset-3
{/html:col} {/html:row}

Column ordering

Easily change the order of our built-in grid columns with .col-md-push-* and .col-md-pull-* modifier classes.

.col-md-3 .col-md-pull-9
.col-md-9 .col-md-push-3

{html:row}
 {html:col class="col-md-9 col-md-push-3"}
  .col-md-3 .col-md-pull-9
{/html:col} {html:col class="col-md-3 col-md-pull-9"} .col-md-9 .col-md-push-3
{/html:col} {/html:row}
