Bootstrap 5 Containers


Bootstrap 5 Containers

You learned from the previous chapter that Bootstrap requires a containing element to wrap site contents.

Containers are used to pad the content inside of them, and there are two container classes available:

  1. The .container class provides a responsive fixed width container
  2. The .container-fluid class provides a full width container, spanning the entire width of the viewport
.container
.container-fluid

Fixed Container

Use the .container class to create a responsive, fixed-width container.

Note that its width (max-width) will change on different screen sizes:

Extra small
<576px
Small
≥576px
Medium
≥768px
Large
≥992px
Extra Large
≥1200px
XXL
≥1400px
max-width 100% 540px 720px 960px 1140px 1320px

Open the example below and resize the browser window to see that the container width will change at different breakpoints:

Example

<div class="container">
  <h1>My First Bootstrap Page</h1>
  <p>This is some text.</p>
</div>

The XXL breakpoint (≥1400px) is new in Bootstrap 5, while the largest breakpoint in Bootstrap 4 is Extra large (≥1200px).


Fluid Container

Use the .container-fluid class to create a full width container, that will always span the entire width of the screen (width is always 100%):

Example

<div class="container-fluid">
  <h1>My First Bootstrap Page</h1>
  <p>This is some text.</p>
</div>

Container Padding

By default, containers have left and right padding, with no top or bottom padding. Therefore, we often use spacing utilities, such as extra padding and margins to make them look even better. For example, .pt-5 means "add a large top padding":

Example

<div class="container pt-5"></div>

Container Border and Color

Other utilities, such as borders and colors, are also often used together with containers:

Example

<div class="container p-5 my-5 border"></div>

<div class="container p-5 my-5 bg-dark text-white"></div>

<div class="container p-5 my-5 bg-primary text-white"></div>

You will learn much more about colors and border utilities in a later chapter.


Responsive Containers

You can also use the .container-sm|md|lg|xl classes to determine when the container should be responsive.

The max-width of the container will change on different screen sizes/viewports:

Class Extra small
<576px
Small
≥576px
Medium
≥768px
Large
≥992px
Extra large
≥1200px
XXL
≥1400px
.container-sm 100% 540px 720px 960px 1140px 1320px
.container-md 100% 100% 720px 960px 1140px 1320px
.container-lg 100% 100% 100% 960px 1140px 1320px
.container-xl 100% 100% 100% 100% 1140px 1320px
.container-xxl 100% 100% 100% 100% 100% 1320px

Example

<div class="container-sm">.container-sm</div>
<div class="container-md">.container-md</div>
<div class="container-lg">.container-lg</div>
<div class="container-xl">.container-xl</div>
<div class="container-xxl">.container-xxl</div>
