title: Gutters
description: Gutters are the padding between your columns, used to responsively space and align content in the Bootstrap grid system.
group: layout
toc: true
---
## 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]({{< docsref "/utilities/spacing" >}}) 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-4`:
{{< example class="bd-example-cols" >}}
<div class="container px-4 text-center">
<div class="row gx-5">
<div class="col">
<div class="p-3">Custom column padding</div>
</div>
<div class="col">
<div class="p-3">Custom column padding</div>
</div>
</div>
</div>
{{< /example >}}
An alternative solution is to add a wrapper around the `.row` with the `.overflow-hidden` class:
{{< example class="bd-example-cols" >}}
<div class="container overflow-hidden text-center">
<div class="row gx-5">
<div class="col">
<div class="p-3">Custom column padding</div>
</div>
<div class="col">
<div class="p-3">Custom column padding</div>
</div>
</div>
</div>
{{< /example >}}
## Vertical gutters
`.gy-*` classes can be used to control the vertical gutter widths within a row when columns wrap to new lines. 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:
{{< example class="bd-example-cols" >}}
<div class="container overflow-hidden text-center">
<div class="row gy-5">
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
</div>
</div>
{{< /example >}}
## Horizontal & vertical gutters
Use `.g-*` classes to control the horizontal and vertical grid gutters. In the example below, we use a smaller gutter width, so there isn't a need for the `.overflow-hidden` wrapper class.
{{< example class="bd-example-cols" >}}
<div class="container text-center">
<div class="row g-2">
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3">Custom column padding</div>
</div>
</div>
</div>
{{< /example >}}
## Row columns gutters
Gutter classes can also be added to [row columns]({{< docsref "/layout/grid#row-columns" >}}). In the following example, we use responsive row columns and responsive gutter classes.
{{< example class="bd-example-cols" >}}
<div class="container text-center">
<div class="row row-cols-2 row-cols-lg-5 g-2 g-lg-3">
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
<div class="col">
<div class="p-3">Row column</div>
</div>
</div>
</div>
{{< /example >}}
## No gutters
The gutters between columns in our predefined grid classes can be removed with `.g-0`. This removes the negative `margin`s 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 that you can continue to use this with all other predefined grid classes (including column widths, responsive tiers, reorders, and more).
{{< example class="bd-example-row" >}}
<div class="row g-0 text-center">
<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>
{{< /example >}}
## Change the gutters
Classes are built from the `$gutters` Sass map which is inherited from the `$spacers` Sass map.
```scss
$grid-gutter-width: 1.5rem;
$gutters: (
0: 0,
1: $spacer * .25,
2: $spacer * .5,
3: $spacer,
4: $spacer * 1.5,
5: $spacer * 3,
);
```
