## About
A **card** is a flexible and extensible content container. It includes options for headers and footers, a wide variety of content, contextual background colors, and powerful display options. If you're familiar with Bootstrap 3, cards replace our old panels, wells, and thumbnails. Similar functionality to those components is available as modifier classes for cards.
## Example
Cards are built with as little markup and styles as possible, but still manage to deliver a ton of control and customization. Built with flexbox, they offer easy alignment and mix well with other Bootstrap components. They have no `margin` by default, so use [spacing utilities]({{< docsref "/utilities/spacing" >}}) as needed.
Below is an example of a basic card with mixed content and a fixed width. Cards have no fixed width to start, so they'll naturally fill the full width of its parent element. This is easily customized with our various [sizing options](#sizing).
Cards support a wide variety of content, including images, text, list groups, links, and more. Below are examples of what's supported.
### Body
The building block of a card is the `.card-body`. Use it whenever you need a padded section within a card.
{{<example>}}
<divclass="card">
<divclass="card-body">
This is some text within a card body.
</div>
</div>
{{</example>}}
### Titles, text, and links
Card titles are used by adding `.card-title` to a `<h*>` tag. In the same way, links are added and placed next to each other by adding `.card-link` to an `<a>` tag.
Subtitles are used by adding a `.card-subtitle` to a `<h*>` tag. If the `.card-title` and the `.card-subtitle` items are placed in a `.card-body` item, the card title and subtitle are aligned nicely.
<pclass="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
<ahref="#"class="card-link">Card link</a>
<ahref="#"class="card-link">Another link</a>
</div>
</div>
{{</example>}}
### Images
`.card-img-top` places an image to the top of the card. With `.card-text`, text can be added to the card. Text within `.card-text` can also be styled with the standard HTML tags.

### List groups
Create lists of content in a card with a flush list group.
{{<example>}}
<divclass="card"style="width: 18rem;">
<ulclass="list-group list-group-flush">
<liclass="list-group-item">An item</li>
<liclass="list-group-item">A second item</li>
<liclass="list-group-item">A third item</li>
</ul>
</div>
{{</example>}}
{{<example>}}
<divclass="card"style="width: 18rem;">
<divclass="card-header">
Featured
</div>
<ulclass="list-group list-group-flush">
<liclass="list-group-item">An item</li>
<liclass="list-group-item">A second item</li>
<liclass="list-group-item">A third item</li>
</ul>
</div>
{{</example>}}
{{<example>}}
<divclass="card"style="width: 18rem;">
<ulclass="list-group list-group-flush">
<liclass="list-group-item">An item</li>
<liclass="list-group-item">A second item</li>
<liclass="list-group-item">A third item</li>
</ul>
<divclass="card-footer">

</div>
</div>
{{</example>}}
### Kitchen sink
Mix and match multiple content types to create the card you need, or throw everything in there. Shown below are image styles, blocks, text styles, and a list group—all wrapped in a fixed-width card.
Cards assume no specific `width` to start, so they'll be 100% wide unless otherwise stated. You can change this as needed with custom CSS, grid classes, grid Sass mixins, or utilities.
### Using grid markup
Using the grid, wrap cards in columns and rows as needed.
You can quickly change the text alignment of any card—in its entirety or specific parts—with our [text align classes]({{< docsref "/utilities/text#text-alignment" >}}).
Cards include a few options for working with images. Choose from appending "image caps" at either end of a card, overlaying images with card content, or simply embedding the image in a card.
### Image caps
Similar to headers and footers, cards can include top and bottom "image caps"—images at the top or bottom of a card.
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text"><small>Last updated 3 mins ago</small></p>
</div>
</div>
{{</example>}}
{{<calloutinfo>}}
Note that content should not be larger than the height of the image. If content is larger than the image the content will be displayed outside the image.
{{</callout>}}
## Horizontal
Using a combination of grid and utility classes, cards can be made horizontal in a mobile-friendly and responsive way. In the example below, we remove the grid gutters with `.g-0` and use `.col-md-*` classes to make the card horizontal at the `md` breakpoint. Further adjustments may be needed depending on your card content.
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
Cards include various options for customizing their backgrounds, borders, and color.
### Background and color
{{<added-in"5.2.0">}}
Set a `background-color` with contrasting foreground `color` with [our `.text-bg-{color}` helpers]({{< docsref "helpers/color-background" >}}). Previously it was required to manually pair your choice of [`.text-{color}`]({{< docsref "/utilities/colors" >}}) and [`.bg-{color}`]({{< docsref "/utilities/background" >}}) utilities for styling, which you still may use if you prefer.
Use [border utilities]({{< docsref "/utilities/borders" >}}) to change just the `border-color` of a card. Note that you can put `.text-{color}` classes on the parent `.card` or a subset of the card's contents as shown below.
In addition to styling the content within cards, Bootstrap includes a few options for laying out series of cards. For the time being, **these layout options are not yet responsive**.
### Card groups
Use card groups to render cards as a single, attached element with equal width and height columns. Card groups start off stacked and use `display: flex;` to become attached with uniform dimensions starting at the `sm` breakpoint.
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
Use the Bootstrap grid system and its [`.row-cols` classes]({{< docsref "/layout/grid#row-columns" >}}) to control how many grid columns (wrapped around your cards) you show per row. For example, here's `.row-cols-1` laying out the cards on one column, and `.row-cols-md-2` splitting four cards to equal width across multiple rows, from the medium breakpoint up.
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
</div>
</div>
</div>
{{</example>}}
Change it to `.row-cols-3` and you'll see the fourth card wrap.
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
</div>
</div>
</div>
{{</example>}}
When you need equal height, add `.h-100` to the cards. If you want equal heights by default, you can set `$card-height: 100%` in Sass.
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
</div>
</div>
</div>
</div>
{{</example>}}
Just like with card groups, card footers will automatically line up.
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
<pclass="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
In `v4` we used a CSS-only technique to mimic the behavior of [Masonry](https://masonry.desandro.com/)-like columns, but this technique came with lots of unpleasant [side effects](https://github.com/twbs/bootstrap/pull/28922). If you want to have this type of layout in `v5`, you can just make use of Masonry plugin. **Masonry is not included in Bootstrap**, but we've made a [demo example]({{< docsref "/examples/masonry" >}}) to help you get started.
## CSS
### Variables
{{<added-in"5.2.0">}}
As part of Bootstrap's evolving CSS variables approach, cards now use local CSS variables on `.card` for enhanced real-time customization. Values for the CSS variables are set via Sass, so Sass customization is still supported, too.
