卡片（Card）

Bootstrap 的卡片提供了一个灵活、可扩展的内容容器，具有多种变体和选项。

关于

卡是一种灵活、可扩展的内容容器。它包括页眉和页脚选项、多种内容、上下文背景颜色以及强大的显示选项。如果您熟悉 Bootstrap 3，那么卡片将取代我们以前的面板、wells和缩略图。卡片的修改器类提供了与这些组件类似的功能。

示例

卡片使用尽可能少的标记和样式构建，但仍能提供大量的控制和自定义功能。卡片采用 flexbox 构建，易于对齐，可与其他 Bootstrap 组件完美搭配。它们默认没有 margin，因此可根据需要使用间距实用工具。

下面是一个具有混合内容和固定宽度的基本卡片示例。卡片一开始没有固定宽度，因此会自然填满父元素的整个宽度。这可以通过我们的各种尺寸选项轻松定制。

Card title

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

Go somewhere

html

<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

卡片支持多种内容，包括图片、文本、列表组、链接等。以下是支持内容的示例。

主体

卡片的构件是.card-body。当您需要在卡片中添加填充部分时，请使用它。

This is some text within a card body.

html

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

标题、文本和链接

卡片标题可通过在<h*>标记中添加.card-title来使用。同样，通过在<a>标记中添加.card-link，可以添加链接并将其放置在彼此旁边。

字幕可通过在<h*>标记中添加.card-subtitle来使用。如果将.card-title和.card-subtitle项放在.card-body项中，卡片标题和副标题就会很好地对齐。

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

图片

.card-img-top 和 .card-img-bottom 分别设置圆角的上角和下角，以匹配卡片的边框。使用 .card-text，可以为卡片添加文本。.card-text中的文本也可以使用标准的 HTML 标签进行样式设置。

尺寸大小

开始时，卡片假设没有特定的 width，因此除非另有说明，否则它们将是 100% 宽。您可以根据需要使用自定义 CSS、网格类、网格 Sass 混合类或实用程序来更改宽度。

使用网格标记

使用网格，根据需要将卡片分栏和分行包装。

卡片包含一些用来处理图片的选项。选择在卡片的任一端附加“image caps”，用卡片内容覆盖图片，或者只是将图象嵌入到卡中。

Image caps

与页首或页尾相似，卡片可以包含顶部或是底部的“Image caps”，即图片是位于卡片的顶部或是底部。

水平

结合使用网格和实用工具类，可以以移动友好和响应迅速的方式使卡片水平放置。在下面的示例中，我们使用.g-0删除了网格槽，并使用.col-md-*类在md断点处使卡片水平。根据您的卡片内容，可能需要进一步调整。

卡片布局

除了为卡片中的内容设计样式外，Bootstrap 还提供了一些用于布局系列卡片的选项。目前，这些布局选项还没有响应。

卡片组

使用卡片组可将卡片呈现为具有等宽等高列的单个附加元素。卡片组开始时是堆叠的，然后使用 display: flex; 从 sm 断点开始以统一的尺寸连接起来。

网格卡片

使用 Bootstrap 网格系统及其 .row-cols类来控制每行显示的网格列数（包裹着卡片）。例如，这里的 .row-cols-1是在一列中显示卡片，而 .row-cols-md-2则是将四张卡片等宽分割到多行中，从中间断点开始往上显示。

需要等高时，可在卡片上添加 .h-100。如果需要默认等高，可以在 Sass 中设置 $card-height: 100% 。

Masonry

在 v4 中，我们使用了一种纯 CSS 技术来模仿类似于 Masonry 的列的行为，但这种技术带来了许多令人不快的副作用。如果您想在 v5 中使用这种布局，可以直接使用 Masonry 插件。Masonry不包含在Bootstrap中，但我们制作了一个演示示例来帮助您入门。

CSS

变量

Added in v5.2.0

作为 Bootstrap 不断发展的 CSS 变量方法的一部分，卡片现在使用.card上的本地 CSS 变量来增强实时自定义功能。CSS 变量的值通过 Sass 设置，因此仍支持 Sass 自定义。

scss/_card.scss

--#{$prefix}card-spacer-y: #{$card-spacer-y};
--#{$prefix}card-spacer-x: #{$card-spacer-x};
--#{$prefix}card-title-spacer-y: #{$card-title-spacer-y};
--#{$prefix}card-title-color: #{$card-title-color};
--#{$prefix}card-subtitle-color: #{$card-subtitle-color};
--#{$prefix}card-border-width: #{$card-border-width};
--#{$prefix}card-border-color: #{$card-border-color};
--#{$prefix}card-border-radius: #{$card-border-radius};
--#{$prefix}card-box-shadow: #{$card-box-shadow};
--#{$prefix}card-inner-border-radius: #{$card-inner-border-radius};
--#{$prefix}card-cap-padding-y: #{$card-cap-padding-y};
--#{$prefix}card-cap-padding-x: #{$card-cap-padding-x};
--#{$prefix}card-cap-bg: #{$card-cap-bg};
--#{$prefix}card-cap-color: #{$card-cap-color};
--#{$prefix}card-height: #{$card-height};
--#{$prefix}card-color: #{$card-color};
