Start by adding an element with a class of .row. This will create a horizontal block to contain vertical columns. Then add elements with a .column class within that row. Specify the widths of each column with the .small-#, .medium-#, and .large-# classes.

Foundation is mobile-first. Code for small screens first, and larger devices will inherit those styles. Customize for larger screens as necessary.

By default `.column` has an alias `.columns` (see the `$grid-column-alias` option) —the only difference is grammar.

Disabling the alias can reduce the Foundation CSS file size from 3 to 5%. It is recommended if the alias is not used.

<div class="row">
  <div class="columns small-2 large-4"><!-- ... --></div>
  <div class="columns small-4 large-4"><!-- ... --></div>
  <div class="columns small-6 large-4"><!-- ... --></div>
</div>
<div class="row">
  <div class="columns large-3"><!-- ... --></div>
  <div class="columns large-6"><!-- ... --></div>
  <div class="columns large-3"><!-- ... --></div>
</div>
<div class="row">
  <div class="columns small-6 large-2"><!-- ... --></div>
  <div class="columns small-6 large-8"><!-- ... --></div>
  <div class="columns small-12 large-2"><!-- ... --></div>
</div>
<div class="row">
  <div class="columns small-3"><!-- ... --></div>
  <div class="columns small-9"><!-- ... --></div>
</div>
<div class="row">
  <div class="columns large-4"><!-- ... --></div>
  <div class="columns large-8"><!-- ... --></div>
</div>
<div class="row">
  <div class="columns small-6 large-5"><!-- ... --></div>
  <div class="columns small-6 large-7"><!-- ... --></div>
</div>
<div class="row">
  <div class="columns large-6"><!-- ... --></div>
  <div class="columns large-6"><!-- ... --></div>
</div>

Small Grids

Small grids expand to large screens easier than large grids cram into small screens.

<div class="row">
  <div class="columns small-2">2</div>
  <div class="columns small-10">10</div>
</div>
<div class="row">
  <div class="columns small-3">3</div>
  <div class="columns small-9">9</div>
</div>

Medium Grid

Medium sized screens will inherit styles from small, unless you specify a different layout using the medium grid classes.

<div class="row">
  <div class="columns medium-2">2</div>
  <div class="columns medium-10">10</div>
</div>
<div class="row">
  <div class="columns medium-3">3</div>
  <div class="columns medium-9">9</div>
</div>

Advanced

Combined Column/Row

If you have just a single column, you can save some markup by combining the .row and .column classes together on the same element. You can still nest more grids inside this container like usual.

Column rows can use sizing classes like .small-8, but only when used as a top-level container—not when nested inside another row.

<div class="column row">
  Row column
</div>

Fluid Row

Normally, a row is always 1200 pixels wide. Make a row completely fluid by adding the .expanded class.

<div class="expanded row">
</div>

Nesting

You can nest the grids indefinitely, though at a certain point it will get absurd.

<div class="row">
  <div class="columns small-8">8
    <div class="row">
      <div class="columns small-8">8 Nested
        <div class="row">
          <div class="columns small-8">8 Nested Again</div>
          <div class="columns small-4">4</div>
        </div>
      </div>
      <div class="columns small-4">4</div>
    </div>
  </div>
  <div class="columns small-4">4</div>
</div>

Offsets

Move blocks up to 11 columns to the right by using classes like .large-offset-1 and .small-offset-3.

<div class="row">
  <div class="columns large-1">1</div>
  <div class="columns large-11">11</div>
</div>
<div class="row">
  <div class="columns large-1">1</div>
  <div class="columns large-10 large-offset-1">10, offset 1</div>
</div>
<div class="row">
  <div class="columns large-1">1</div>
  <div class="columns large-9 large-offset-2">9, offset 2</div>
</div>
<div class="row">
  <div class="columns large-1">1</div>
  <div class="columns large-8 large-offset-3">8, offset 3</div>
</div>

Incomplete Rows

In order to work around browsers’ different rounding behaviors, Foundation will float the last column in a row to the right so the edge aligns. If your row doesn’t have a count that adds up to 12 columns, you can tag the last column with a class of .end in order to override that behavior. Alternatively, you can set the $grid-column-align-edge variable to false to turn off this behavior entirely.

<div class="row">
  <div class="columns medium-3">3</div>
  <div class="columns medium-3">3</div>
  <div class="columns medium-3">3</div>
</div>
<div class="row">
  <div class="columns medium-3">3</div>
  <div class="columns medium-3">3</div>
  <div class="columns medium-3 end">3 end</div>
</div>

Gutters

Responsive Gutters

The grid gutter—the space between two columns in a row, and the space between the edge of a grid and the edge of the page—is responsive, and becomes larger on larger screens.

Breakpoint	Gutter Size
`small`	20px
`medium`	30px

If you’re using the Sass version of Foundation, you can change these defaults by editing the $grid-column-gutter variable map:

$grid-column-gutter: (
  small: 20px,
  medium: 30px,
);

To add more gutter definitions, add new lines to the map. The breakpoint names used here must match a breakpoint name in your project’s $breakpoints map.

Static Gutters

If you prefer using one gutter size for every breakpoint, just use a single number for the $grid-column-gutter variable:

$grid-column-gutter: 30px;

You can also explicitly set the gutter size for a particular grid row by adding the .gutter-[size] class. This is useful when your using responsive gutters but specific components need static gutters.

<div class="row gutter-small">
  <div class="columns">This grid always has small gutters</div>
</div>

Collapse/Uncollapse Rows

There are times when you won’t want each media query to be collapsed or uncollapsed. In this case, use the media query size you want and collapse or uncollapse and add that to your row element. Example shows gutters at small and medium and no gutters on large and up.

<div class="row medium-uncollapse large-collapse">
  <div class="columns small-6">
    Removes gutter at large media query
  </div>
  <div class="columns small-6">
    Removes gutter at large media query
  </div>
</div>

On a small screen, I have gutters!

On a medium screen, I have gutters!

On a large screen, I have no gutters!

On a small screen, I have gutters!

On a medium screen, I have gutters!

On a large screen, I have no gutters!

Centered Columns

Center your columns by adding a class of .small-centered to your column. Large will inherit small centering by default, but you can also center solely on large by applying a .large-centered class. To uncenter on large screens, use .large-uncentered.

<div class="row">
  <div class="columns small-3 small-centered">3 centered</div>
</div>
<div class="row">
  <div class="columns small-6 large-centered">6 centered</div>
</div>
<div class="row">
  <div class="columns small-9 small-centered large-uncentered">9 centered</div>
</div>
<div class="row">
  <div class="columns small-11 small-centered">11 centered</div>
</div>

Source Ordering

Using these source ordering classes, you can shift columns around between our breakpoints. This means if you place sub-navigation below main content on small displays, you have the option to position the sub-navigation on either the left or right of the page for large displays. Prefix push/pull with the size of the device you want to apply the styles to. .medium-push-#, .large-push-# is the syntax you’ll use. Use the number 0 instead to reset a push/pull, such as .medium-push-0 or .large-pull-0.

<div class="row">
  <div class="columns small-10 small-push-2">10</div>
  <div class="columns small-2 small-pull-10">2, last</div>
</div>
<div class="row">
  <div class="columns large-9 large-push-3">9</div>
  <div class="columns large-3 large-pull-9">3, last</div>
</div>
<div class="row">
  <div class="columns large-8 large-push-4">8</div>
  <div class="columns large-4 large-pull-8">4, last</div>
</div>
<div class="row">
  <div class="columns small-5 small-push-7 medium-7 medium-push-5">7</div>
  <div class="columns small-7 small-pull-5 medium-5 medium-pull-7">5, last</div>
</div>
<div class="row">
  <div class="columns medium-6 medium-push-6">6</div>
  <div class="columns medium-6 medium-pull-6">6, last</div>
</div>

Block Grids

Block grids are a shorthand way to create equally-sized columns. Add a class of the format .[size]-up-[n] to change the number of columns within the row. By default, the max number of columns you can use with block grid are 8. Adding the .column-block class to columns will apply a bottom margin equal to the width of gutters.

Building Semantically

Our grid CSS is generated with a powerful set of Sass mixins, which you can use in your own code to build a semantic grid.

Rows

.container {
  @include grid-row;
}

Columns

Use the grid-column() mixin to create a column. There are a number of ways to define the width of the column.

.main-content {
  // Use the full column count (100%)
  @include grid-column;

  // Use a column count (33%);
  @include grid-column(4);

  // Use a percentage (15%)
  @include grid-column(15%);

  // Use a custom fraction (20%)
  @include grid-column(1 of 5);
}

The grid column calculator can also be accessed as a function. This gives you the percentage value, without any of the grid column CSS.

.main-content {
  width: grid-column(1 of 7);
}

.centered-column {
  @include grid-column-position(center);
}

Multiple Grids

By default, all grids use the number of columns set by the $grid-column-count variable. However, this can be selectively overridden within an instance of a row.

In this example, the grid is 16 columns instead of the normal 12. Any references to column math inside the mixin will use the new column count.

.container {
  @include grid-row(16) {
    .main-content {
      // 11/16 = 68.75%
      @include grid-column(11);
    }

    .sidebar {
      // 5/16 = 31.25%
      @include grid-column(5);
    }
  }
}

You can also temporarily change the grid context without outputting any row CSS, by using the grid-context() mixin.

@include grid-context(7) {
  .sidebar {
    @include grid-column(4);
  }
}

Every other grid feature, from sizing to offsets to source ordering, can also be accessed with a mixin. Pair them with the breakpoint() mixin to make your grid responsive.

.main-content {
  // The mixins have shorthands, too!
  @include grid-col;

  @include breakpoint(medium) {
    // Changes size only
    @include grid-col-size(8);

    // Changes position only
    @include grid-col-pos(4);
  }
}

Custom Block Grid

Use the grid-layout() mixin to create your own block grid. By default the mixin takes 3 parameters:

The padding value can be set to $grid-column-gutter to use the values from that map. This will then generate different paddings at different breakpoints. Alternatively supply a numeric value (without a unit type) to output a static rem value.

.gallery {
  @include grid-layout(3, '.gallery-item', $grid-column-gutter);
}

.gallery > .gallery-item {
  width: 33.33333%;
  float: left;
  padding-left: 0.625rem;
  padding-right: 0.625rem;
}

@media screen and (min-width: 40em) {
  .gallery > .gallery-item {
    padding-left: 0.9375rem;
    padding-right: 0.9375rem;
  }
}

.gallery > .gallery-item:nth-of-type(1n) {
  clear: none;
}

.gallery > .gallery-item:nth-of-type(3n+1) {
  clear: both;
}

.gallery > .gallery-item:last-child {
  float: left;
}
