Cards

Bootstrap’s cards provide a flexible and extensible content container with multiple variants and options.

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 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.

  2.   <img src="..." class="card-img-top" alt="...">
  3.   <div class="card-body">
  4.     <h5 class="card-title">Card title</h5>
  5.     <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
  6.     <a href="#" class="btn btn-primary">Go somewhere</a>
  7.   </div>
  8. </div>

Content 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.

  1. <div class="card">
  2.   <div class="card-body">
  3.     This is some text within a card body.
  4.   </div>
  5. </div>

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.

  3.     <h5 class="card-title">Card title</h5>
  4.     <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
  5.     <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
  6.     <a href="#" class="card-link">Card link</a>
  7.     <a href="#" class="card-link">Another link</a>
  8.   </div>
  9. </div>

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.

Sizing

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.

Images

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.

Card - 图19

  1. <div class="card bg-dark text-white">
  2.   <img src="..." class="card-img" alt="...">

  5.     <p class="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>
  6.     <p class="card-text">Last updated 3 mins ago</p>
  7.   </div>
  8. </div>

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.

Card styles

Cards include various options for customizing their backgrounds, borders, and color.

Background and color

Use text and background utilities to change the appearance of a card.

Conveying meaning to assistive technologies

Using color to add meaning only provides a visual indication, which will not be conveyed to users of assistive technologies – such as screen readers. Ensure that information denoted by the color is either obvious from the content itself (e.g. the visible text), or is included through alternative means, such as additional text hidden with the .sr-only class.

Border

Use border utilities 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 use display: flex; to achieve their uniform sizing.

<div class="card-group">
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
</div>

When using card groups with footers, their content will automatically line up.

    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
    </div>
    <div class="card-footer">

  <div class="card">

  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
    </div>
    <div class="card-footer">

    </div>

Card decks

Need a set of equal width and height cards that aren’t attached to one another? Use card decks.

<div class="card-deck">
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
</div>

Just like with card groups, card footers in decks will automatically line up.

<div class="card-deck">
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="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>
    </div>
    <div class="card-footer">
      <small class="text-muted">Last updated 3 mins ago</small>
    </div>
  </div>
</div>

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.

      <p class="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>

      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <img src="..." class="card-img-top" alt="...">

  <div class="card p-3 text-right">

  <div class="card">
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This is another card with title and supporting text below. This card has some additional content to make it slightly taller overall.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
</div>

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.

.card-columns {
  @include media-breakpoint-only(lg) {
    column-count: 4;
  }
  @include media-breakpoint-only(xl) {
    column-count: 5;
  }
}
