Gutters
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 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>
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 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>
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.
<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>
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 px-3">
<div class="col-sm-6 col-md-8 border">.col-sm-6 .col-md-8</div>
<div class="col-6 col-md-4 border">.col-6 .col-md-4</div>
</div>
