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]({{ site.baseurl }}/docs/{{ site.docs_version }}/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.

Go somewhereContent types
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.
{% capture 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.

Card link Another linkImages
.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.
{% capture example %}
- Cras justo odio
- Dapibus ac facilisis in

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.

Go somewhereSizing
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.

Using custom CSS
Use custom CSS in your stylesheets or as inline styles to set a width.

Go somewhereImages
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.

Image overlays
Turn an image into a card background and overlay your card's text. Depending on the image, you may or may not need additional styles or utilities.

{% capture callout %} 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. {% endcapture %} {% include callout.html content=callout type="info" %}
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 .no-gutters and use .col-md-* classes to make the card horizontal at the md breakpoint. Further adjustments may be needed depending on your card content.

Card styles
Cards include various options for customizing their backgrounds, borders, and color.
Background and color
Use [text and background utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/utilities/colors/) to change the appearance of a card.
{% capture example %} {% for color in site.data.theme-colors %}
{{ color.name | capitalize }} card title
Some quick example text to build on the card title and make up the bulk of the card's content.
{% include callout-warning-color-assistive-technologies.md %}
Border
Use [border utilities]({{ site.baseurl }}/docs/{{ site.docs_version }}/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.
{% capture example %} {% for color in site.data.theme-colors %}
{{ color.name | capitalize }} card title
Some quick example text to build on the card title and make up the bulk of the card's content.
Mixins utilities
You can also change the borders on the card header and footer as needed, and even remove their background-color with .bg-transparent.

Card layout
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.
{% capture example %}

Grid cards
Use the Bootstrap grid system and its [.row-cols classes]({{ site.baseurl }}/docs/{{ site.docs_version }}/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.

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.

Card columns
Cards can be organized into Masonry-like columns with just CSS by wrapping them in .card-columns. Cards are built with CSS column properties instead of flexbox for easier alignment. Cards are ordered from top to bottom and left to right.
Heads up! Your mileage with card columns may vary. To prevent cards breaking across columns, we must set them to display: inline-block as column-break-inside: avoid isn't a bulletproof solution yet.

Card columns can also be extended and customized with some additional code. Shown below is an extension of the .card-columns class using the same CSS we use—CSS columns— to generate a set of responsive tiers for changing the number of columns.
{% highlight scss %} .card-columns { @include media-breakpoint-only(lg) { column-count: 4; } @include media-breakpoint-only(xl) { column-count: 5; } } {% endhighlight %}
