Columns

A simple way to build responsive columns

To build a grid, just:

  1. Add a columns container
  2. Add as many column elements as you want

Each column will have an equal width, no matter the number of columns.

First column

Second column

Third column

Fourth column

<div class="columns">
  <div class="column">
    First column
  </div>
  <div class="column">
    Second column
  </div>
  <div class="column">
    Third column
  </div>
  <div class="column">
    Fourth column
  </div>
</div>

Sizes

If you want to change the size of a single column, you can use one the following classes:

  • is-three-quarters
  • is-two-thirds
  • is-half
  • is-one-third
  • is-one-quarter

The other columns will fill up the remaining space automatically.

is-three-quarters

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

      <code class="html">is-one-quarter</code>
    </p>
  </div>
  <div class="column">
    <p class="notification is-success">Auto</p>
  </div>
</div>

12 columns

As the grid can be divided into 12 columns, there are size classes for each division:

  • is-2
  • is-3
  • is-4
  • is-5
  • is-6
  • is-7
  • is-8
  • is-9
  • is-10
  • is-11

Naming

Each modifier class is named after how many columns you want out of 12. So if you want 7 columns out of 12, use is-7.

Offset

While you can use empty columns (like <div class="column"></div>) to create horizontal space around .column elements, you can also use offset modifiers like .is-offset-x:

is-half
is-offset-one-quarter

is-4
is-offset-8

is-11
is-offset-1 

<div class="columns is-mobile">
  <div class="column is-half is-offset-one-quarter"></div>
</div>

<div class="columns is-mobile">
  <div class="column is-4 is-offset-8"></div>
</div>

<div class="columns is-mobile">
  <div class="column is-11 is-offset-1"></div>
</div>

Responsiveness

By default, columns are only activated from tablet onwards. This means columns are stacked on top of each other on mobile.

If you want columns to work on mobile too, just add the is-mobile modifier on the columns container:

1

2

3

4

<div class="columns is-mobile">
  <div class="column">1</div>
  <div class="column">2</div>
  <div class="column">3</div>
  <div class="column">4</div>
</div>

Resize

If you want to see the difference, resize your browser and see when the columns are stacked and when they are horizontally distributed.

If you only want columns on desktop, just use the is-desktop modifier on the columns container:

1

2

3

4

<div class="columns is-desktop">
  <div class="column">1</div>
  <div class="column">2</div>
  <div class="column">3</div>
  <div class="column">4</div>
</div>

Different sizes per breakpoint

You can define a column size for each viewport size: mobile, tablet, and desktop.

is-half-mobile
is-one-third-tablet
is-one-quarter-desktop

1

1

1

1

Resize

If you want to see these classes in action, resize your browser window and see how the same column varies in width at each breakpoint.

<div class="columns is-mobile">
  <div class="column is-half-mobile is-one-third-tablet is-one-quarter-desktop">
    <code>is-half-mobile</code><br>
    <code>is-one-third-tablet</code><br>
    <code>is-one-quarter-desktop</code>
  </div>
  <div class="column">1</div>
  <div class="column">1</div>
  <div class="column">1</div>
  <div class="column">1</div>
</div>

Nesting

You can nest columns to have more flexibility in your design. You only need to follow this structure:

  • columns: top-level columns container
    • column
      • columns: nested columns
        • column and so on…

The difference with multiline columns is the order in the HTML code: all the blue columns appear before the red ones. Resize to a narrower viewport to see the result.

First column

First nested column

Second nested column

<div class="columns">
  <div class="column">

    <div class="columns is-mobile">
      <div class="column">
        First nested column
      </div>
      <div class="column">
        Second nested column
      </div>
    </div>
  </div>
  <div class="column">
    Second column
    <div class="columns is-mobile">
      <div class="column is-half">
        50%
      </div>
      <div class="column">
        Auto
      </div>
      <div class="column">
        Auto
      </div>
    </div>
  </div>
</div>

Multiline

Whenever you want to start a new line, you can close a columns container and start a new one. But you can also add the is-multiline modifier and add more column elements that would fit in a single row.

is-one-quarter

is-one-quarter

is-one-quarter

is-one-quarter

is-half

is-one-quarter

is-one-quarter

is-one-quarter

Auto

<div class="columns is-multiline is-mobile">
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-half">
    <code>is-half</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column">
    Auto
  </div>
</div>

Gapless

If you want to remove the space between the columns, add the is-gapless modifier on the columns container:

First column

Second column

Third column

Fourth column

<div class="columns is-gapless">
  <div class="column">First column</div>
  <div class="column">Second column</div>
  <div class="column">Third column</div>
  <div class="column">Fourth column</div>
</div>

You can combine it with the is-multiline modifier:

is-one-quarter

is-one-quarter

is-one-quarter

is-one-quarter

is-half

is-one-quarter

is-one-quarter

is-one-quarter

Auto

<div class="columns is-gapless is-multiline is-mobile">
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-half">
    <code>is-half</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column is-one-quarter">
    <code>is-one-quarter</code>
  </div>
  <div class="column">
    Auto
  </div>
</div>

Narrow column

If you want a column to only take the space it needs, use the is-narrow modifier. The other column(s) will fill up the remaining space.

Narrow column

This column is only 200px wide.

Flexible column

This column will take up the remaining space available.

<div class="columns">
  <div class="column is-narrow">
    <div class="box" style="width: 200px;">
      <p class="title is-5">Narrow column</p>
      <p class="subtitle">This column is only 200px wide.</p>
    </div>
  </div>
  <div class="column">
    <div class="box">
      <p class="title is-5">Flexible column</p>
      <p class="subtitle">This column will take up the remaining space available.</p>
    </div>
  </div>
</div>

As for the size modifiers, you can have narrow columns for different breakpoints:

  • is-narrow-mobile
  • is-narrow-tablet
  • is-narrow-desktop
