Gutters
Gutters are the padding between your columns, used to responsively space and align content in the Bootstrap grid system.
How they work
-
Gutters are the gaps between column content, created by horizontal
padding. We setpadding-rightandpadding-lefton each column, and use negativemarginto 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-4:
<div class="container px-4">
<div class="row gx-5">
<div class="col">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Custom column padding</div>
</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">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Custom column padding</div>
</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">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</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-2">
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</div>
<div class="col-6">
<div class="p-3 border bg-light">Custom column padding</div>
</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">
<div class="row row-cols-2 row-cols-lg-5 g-2 g-lg-3">
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</div>
<div class="col">
<div class="p-3 border bg-light">Row column</div>
</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.
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>Change the gutters
Classes are built from the $gutters Sass map which is inherited from the $spacers Sass map.
$grid-gutter-width: 1.5rem;
$gutters: (
0: 0,
1: $spacer * .25,
2: $spacer * .5,
3: $spacer,
4: $spacer * 1.5,
5: $spacer * 3,
);
