卡片(Cards)

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

关于

卡片(card) 是一种灵活且可扩展的内容容器。它可以包含页眉和页脚、支持各种内容、情境相关的背景色、强大的 display 支持。如果你熟悉 Bootstrap 3,你将会发现卡片(card)取代了以前的面板(panels)、wells 以及缩略图(thumbnails)等组件。与这些组件类似的功能可以通过卡片(card)的修改器类(modifier class)来实现。

示例

卡片(card)由尽可能少的 HTML 标签和 CSS 样式构建而成,但仍然能够提供大量的控制和定制能力。由于使用 flexbox 布局,它易于对齐,并且能够很好地与其它 Bootstrap 组件组合使用。默认情况下,卡片(card)没有 margin(外边距),因此可根据需求使用 spacing utilities

以下是一个基本的卡片(card)示例,它包含了混合型的内容,并且宽度固定。卡片(card)初始时是没有设置固定宽度的,因此它们天生就会填充其父元素的整个宽度。通过使用各种 sizing options 可以轻松地控制其宽度。

Card title

Some quick example text to build on the card title and make up the bulk of the card's content.

Go somewhere
<div class="card" style="width: 18rem;">
  <img src="..." class="card-img-top" alt="...">
  <div class="card-body">
    <h5 class="card-title">Card title</h5>
    <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>
    <a href="#" class="btn btn-primary">Go somewhere</a>
  </div>
</div>

内容类型

卡片(card)支持多种类型的内容,包括图片、文本、列表组、链接等。以下均有示例。

主体(Body)

.card-body 是卡片(card)的组成部分。只要你需要填充卡片(card)就需要使用它。

This is some text within a card body.
<div class="card">
  <div class="card-body">
    This is some text within a card body.
  </div>
</div>

标题、文本和链接

卡片(card)的标题是通过为 <h*> 标签添加 .card-title 类来实现的。以同样的方式,链接(links)是通过为 <a> 标签添加 .card-link 类实现的,添加的链接将并排放置在一起。

副标题(Subtitles)是通过为 <h*> 标签添加 .card-subtitle 类实现的。如果 .card-title.card-subtitle 被同时放在 .card-body 内,则卡片(card)的标题和副标题会被漂亮地对齐。

    <a href="#" class="card-link">Card link</a>
    <a href="#" class="card-link">Another link</a>
  </div>
</div>

图片

.card-img-top 能够将图片放置于卡片(card)的顶部。通过 .card-text 可以向卡片(card)添加文本。位于 .card-text 内的文本还可以通过标准的 HTML 标签添加样式。

Sizing

卡片(card)初始时是没有设置固定 width (宽度)的,所以除非另有说明,否则它们都是 100% 宽度。你可以根据需要使用自定义的 CSS、栅格类(grid classes)、栅格相关的 Sass mixins 或工具类来更改其宽度。

Using grid markup

Using the grid, wrap cards in columns and rows as needed.

图片

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.

  </div>
</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.

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.

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 .visually-hidden class.

边框

You can also change the borders on the card header and footer as needed, and even remove their background-color with .bg-transparent.

Header
Success card title

Some quick example text to build on the card title and make up the bulk of the card's content.

<div class="card border-success mb-3" style="max-width: 18rem;">
  <div class="card-header bg-transparent border-success">Header</div>
  <div class="card-body text-success">
    <h5 class="card-title">Success card title</h5>
    <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>

  <div class="card-footer bg-transparent border-success">Footer</div>

卡片(card)的布局

除了在卡片(card)中设置内容的样式外,Bootstrap 还提供了一些用于排列多个卡片(card)的类。目前,这些用于排列卡片(card)的类并不支持响应式布局

卡片(card)组

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.

Grid cards

Use the Bootstrap grid system and its .row-cols classes 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.

Masonry

In v4 we used a CSS-only technique to mimic the behavior of Masonry-like columns, but this technique came with lots of unpleasant side effects. 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 to help you get started.
