# Bootstrap 5 Containers

Bootstrap 5 containers for AdminKit: default, responsive (.container-sm to .container-xxl) and fluid containers, with max-widths per breakpoint.

## 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.

<table class="table">
  <thead>
    <tr>
      <td class="border-dark"></td>
      <th scope="col">
        Extra small<br />
        <span class="fw-normal">&lt;576px</span>
      </th>
      <th scope="col">
        Small<br />
        <span class="fw-normal">&ge;576px</span>
      </th>
      <th scope="col">
        Medium<br />
        <span class="fw-normal">&ge;768px</span>
      </th>
      <th scope="col">
        Large<br />
        <span class="fw-normal">&ge;992px</span>
      </th>
      <th scope="col">
        X-Large<br />
        <span class="fw-normal">&ge;1200px</span>
      </th>

      <td class="text-muted">100%</td>
      <td class="text-muted">100%</td>
      <td class="text-muted">100%</td>
      <td class="text-muted">100%</td>
      <td class="text-muted">100%</td>
    </tr>

## Default container

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

```html
<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-width`s 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`.

```html
<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.

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