Gutters

Gutters are the padding between your columns, used to responsively space and align content in the Bootstrap grid system.

Quick reference

How they work

• Gutters are the gaps between column content, created by horizontal padding. We set padding-right and padding-left on each column, and use negative margin to offset that at the start and end of each row to align content.

• Gutters start at 1.5rem (24px) wide. This allows us to match our grid to the padding and margin spacers scale.

• Gutters can be responsively adjusted. Use breakpoint-specific gutter classes to modify horizontal gutters, vertical gutters, and all gutters.

Horizontal gutters

.gx-* classes can be used to control the horizontal gutter widths. The .container or .container-fluid parent may need to be adjusted if larger gutters are used too to avoid unwanted overflow, using a matching padding utility.

For example, in the following example we’ve increased the padding with .px-5:

<div class="container">
  <div class="row gx-5">
    <div class="col">
      Custom column padding
    </div>
    <div class="col">
      Custom column padding
    </div>
  </div>
</div>

An alternative solution is to add a wrapper around the .row with the .overflow-hidden class:

<div class="container overflow-hidden">
  <div class="row gx-5">
    <div class="col">
      Custom column padding
    </div>
    <div class="col">
      Custom column padding
    </div>
  </div>
</div>

Vertical gutters

.gy-* classes can be used to control the vertical gutter widths. Like the horizontal gutters, the vertical gutters can cause some overflow below the .row at the end of a page. If this occurs, you add a wrapper around .row with the .overflow-hidden class:

<div class="container overflow-hidden">
  <div class="row gy-5">
    <div class="col-6">
      Custom column padding
    </div>
    <div class="col-6">
      Custom column padding
    </div>
    <div class="col-6">
      Custom column padding
    </div>
    <div class="col-6">
      Custom column padding
    </div>
  </div>
</div>

Horizontal & vertical gutters

.g-* classes can be used to control the horizontal gutter widths, for the following example we use a smaller gutter width, so there won’t be a need to add the .overflow-hidden wrapper class.

<div class="container">
  <div class="row g-3">
    <div class="col-6">
      Custom column padding
    </div>
    <div class="col-6">
      Custom column padding
    </div>
    <div class="col-6">
      Custom column padding
    </div>
    <div class="col-6">
      Custom column padding
    </div>
  </div>
</div>

Row columns gutters

Gutter classes can also be added to row columns. In the following example, we use responsive row columns and responsive gutter classes.

<div class="container text-center bg-striped-purple px-0">
  <div class="row row-cols-2 row-cols-lg-5 g-1 g-lg-3">
    <div class="col">
      Row column
    </div>
    <div class="col">
      Row column
    </div>
    <div class="col">
      Row column
    </div>
    <div class="col">
      Row column
    </div>
    .....
  </div>
</div>

No gutters

The gutters between columns in our predefined grid classes can be removed with .g-0. This removes the negative margins from .row and the horizontal padding from all immediate children columns.

Need an edge-to-edge design? Drop the parent .container or .container-fluid and add .mx-0 to the .row to prevent overflow.

In practice, here’s how it looks. Note you can continue to use this with all other predefined grid classes (including column widths, responsive tiers, reorders, and more).

<div class="row g-0">
  <div class="col-sm-6 col-md-8">.col-sm-6 .col-md-8</div>
  <div class="col-6 col-md-4">.col-6 .col-md-4</div>
</div>

Breakpoints and media queries

All gutter utilities that supports responsive at specific breakpoints, using the following format g*-{breakpoint}-{*} for xs, sm, md, lg, xl, and xxl.

Here are all the support classes:

• .g-sm-0
• .g-sm-1
• .g-sm-2
• ……
