Bootstrap 5 Containers

Containers

Containers are basic building blocks of AdminKit for Bootstrap that contain, pad, and align your content within a given device or viewport.

How they work

Containers are the most basic layout element in Bootstrap and are required when using our default grid system. Containers are used to contain, pad, and (sometimes) center the content within them. While containers can be nested, most layouts do not require a nested container.

Bootstrap comes with three different containers:

  • .container, which sets a max-width at each responsive breakpoint
  • .container-fluid, which is width: 100% at all breakpoints
  • .container-{breakpoint}, which is width: 100% until the specified breakpoint

The table below illustrates how each container’s max-width compares to the original .container and .container-fluid across each breakpoint.

Extra small
<576px
Small
≥576px
Medium
≥768px
Large
≥992px
X-Large
≥1200px
.container 100% 540px 720px 960px 1200px
.container-sm 100% 540px 720px 960px 1200px
.container-md 100% 100% 720px 960px 1200px
.container-lg 100% 100% 100% 960px 1200px
.container-xl 100% 100% 100% 100% 1200px
.container-fluid 100% 100% 100% 100% 100%

Default container

Our default .container class is a responsive, fixed-width container, meaning its max-width changes at each breakpoint.

<div class="container">
  <!-- Content here -->
</div>

Responsive containers

Responsive containers allow you to specify a class that is 100% wide until the specified breakpoint is reached, after which we apply max-widths for each of the higher breakpoints. For example, .container-sm is 100% wide to start until the sm breakpoint is reached, where it will scale up with md, lg, xl, and xxl.

<div class="container-sm">100% wide until small breakpoint</div>
<div class="container-md">100% wide until medium breakpoint</div>
<div class="container-lg">100% wide until large breakpoint</div>
<div class="container-xl">100% wide until extra large breakpoint</div>

Fluid containers

Use .container-fluid for a full width container, spanning the entire width of the viewport.

<div class="container-fluid">
  ...
</div>
