Bootstrap 3 Grids

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 .


Bootstrap's grid system allows up to 12 columns across the page.

If you do not want to use all 12 columns individually, you can group the columns together to create wider columns:

Grid Classes

The Bootstrap grid system has four classes:
  • xs (for phones)
  • sm (for tablets)
  • md (for desktops)
  • lg (for larger desktops)

The classes above can be combined to create more dynamic and flexible layouts.


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.

Example
.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
    
        <div class="row">
                <div class="col-xs-12 col-md-8">.col-xs-12 .col-md-8</div>
                <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
        </div>

        <div class="row">
                <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
                <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
                <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
        </div>

        <div class="row">
                <div class="col-xs-6">.col-xs-6</div>
                <div class="col-xs-6">.col-xs-6</div>
        </div>
    

Example: Mobile, tablet, desktop

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

Example
.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

        <div class="row">
                <div class="col-xs-12 col-sm-6 col-md-8">.col-xs-12 .col-sm-6 .col-md-8</div>
                <div class="col-xs-6 col-md-4">.col-xs-6 .col-md-4</div>
        </div>
        <div class="row">
                <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
                <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
                <!-- Optional: clear the XS cols if their content doesn't match in height -->
                <div class="clearfix visible-xs-block"></div>
                <div class="col-xs-6 col-sm-4">.col-xs-6 .col-sm-4</div>
        </div>
    

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.

Example
.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.

        <div class="row">
                <div class="col-xs-9">.col-xs-9</div>
                <div class="col-xs-4">.col-xs-4<br>Since 9 + 4 = 13 &gt; 12, this 4-column-wide div gets wrapped onto a new line as one contiguous unit.</div>
                <div class="col-xs-6">.col-xs-6<br>Subsequent columns continue along the new line.</div>
        </div>
    

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

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

        <div class="row">
                <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
                <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>

                <!-- Add the extra clearfix for only the required viewport -->
                <div class="clearfix visible-xs-block"></div>

                <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
                <div class="col-xs-6 col-sm-3">.col-xs-6 .col-sm-3</div>
        </div>
    

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.

Example
.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

        <div class="row">
                <div class="col-md-4">.col-md-4</div>
                <div class="col-md-4 col-md-offset-4">.col-md-4 .col-md-offset-4</div>
        </div>
        <div class="row">
                <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
                <div class="col-md-3 col-md-offset-3">.col-md-3 .col-md-offset-3</div>
        </div>
        <div class="row">
                <div class="col-md-6 col-md-offset-3">.col-md-6 .col-md-offset-3</div>
        </div>
    

Nesting columns

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).

Example
Level 1: .col-sm-9
Level 2: .col-xs-8 .col-sm-6
Level 2: .col-xs-4 .col-sm-6

        <div class="row">
            <div class="col-sm-9">
                    Level 1: .col-sm-9
                    <div class="row">
                            <div class="col-xs-8 col-sm-6">Level 2: .col-xs-8 .col-sm-6</div>
                            <div class="col-xs-4 col-sm-6">Level 2: .col-xs-4 .col-sm-6</div>
                    </div>
            </div>
        </div>
    

Column ordering

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

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

        <div class="row">
                <div class="col-md-9 col-md-push-3">.col-md-9 .col-md-push-3</div>
                <div class="col-md-3 col-md-pull-9">.col-md-3 .col-md-pull-9</div>
        </div>
