卡片

Bootstrap 的卡片提供了一个具有多种变体和选项的灵活且可扩展的内容容器。

在本页

关于

卡片是一种灵活且可扩展的内容容器。它包括页眉和页脚选项、各种内容、上下文背景颜色和强大的显示选项。如果您熟悉 Bootstrap 3，卡片将取代我们的旧面板、well和缩略图。与这些组件类似的功能可用作卡片的修饰符类。

例子

卡片是用尽可能少的标记和样式构建的，但仍然设法提供大量的控制和定制。它们使用 flexbox 构建，可以轻松对齐并与其他 Bootstrap 组件很好地混合。默认情况下没有margin，因此请根据需要使用间距实用程序。

下面是一个包含混合内容和固定宽度的基本卡片示例。卡片没有固定的起始宽度，因此它们自然会填满其父元素的整个宽度。这很容易通过我们的各种尺码选项进行定制。

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，包括图像、文本、列表组、链接等。以下是所支持内容的示例。

内容

卡片的构建块是.card-body. 只要您需要卡片中的填充部分，就可以使用它。

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

卡片标题通过添加.card-title到<h*>标签来使用。以同样的方式，通过添加.card-link到<a>标签来添加链接并将它们彼此相邻放置。

通过在<h*>标签中添加.card-subtitle来使用副标题。如果将.card-title和.card-subtitle项目放在一个.card-body项目中，则卡片标题和副标题会很好地对齐。

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

图片

.card-img-top将图像放置在卡片顶部。使用.card-text，可以将文本添加到卡片中。.card-text中的文本也可以使用标准 HTML 标签设置样式。

尺寸

卡片假设开始没有特定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 混合宏或实用程序更改此设置。

使用网格标记

使用网格，根据需要将卡片包裹在列和行中。

卡片包括一些用于处理图像的选项。选择在卡片的两端附加“图像帽”，用卡片内容覆盖图像，或者简单地将图像嵌入卡片中。

图片帽

与页眉和页脚类似，卡片可以包括顶部和底部的“图像帽”——卡片顶部或底部的图像。

水平布局

使用网格和实用程序类的组合，可以以移动友好且响应迅速的方式将卡片制作成水平的。在下面的示例中，我们删除了网格间距.g-0并使用.col-md-*类使卡片在md断点处水平。根据您的卡片内容，可能需要进一步调整。

向辅助技术传达意义

使用颜色来添加含义仅提供视觉指示，不会将其传达给辅助技术的用户——例如屏幕阅读器。确保用颜色表示的信息要么从内容本身（例如可见文本）中显而易见，要么通过其他方式包含在内，例如隐藏在.visually-hidden类中的附加文本。

边框

使用边框实用程序仅更改卡片的border-color。请注意，您可以将.text-{color}类放在父级.card或卡片内容的子集上，如下所示。

您还可以根据需要更改卡片页眉和页脚的边框，甚至可以删除它们background-color的.bg-transparent.

卡片布局

除了为卡片中的内容设置样式外，Bootstrap 还包括一些用于布置卡片系列的选项。目前，这些布局选项还不是响应式。

卡组

使用卡片组将卡片呈现为具有相同宽度和高度列的单个附加元素。卡片组从堆叠开始，并用display: flex;从断点sm开始以统一尺寸连接。

网格布局卡片

使用 Bootstrap 网格系统及其.row-cols类来控制每行显示的网格列数（包裹在卡片周围）。例如，此处.row-cols-1将卡片布置在一列上，并.row-cols-md-2从中间断点向上将四张卡片分成多行等宽。

当您需要相同的高度时，添加.h-100到卡片中。如果你想要默认等高，你可以在 Sass 中设置$card-height: 100%。

Masonry

在v4我们使用纯 CSS 技术来模仿类似Masonry的栅格的行为，但是这种技术带来了很多令人不快的副作用。如果你想在v5中有这种类型的布局，你可以使用 Masonry 插件。Bootstrap 中不包含 Masonry，但我们制作了一个演示示例来帮助您入门。

CSS

变量

添加于 v5.2.0

作为 Bootstrap 不断发展的 CSS 变量方法的一部分，卡片现在使用本地 CSS 变量.card来增强实时定制。CSS 变量的值是通过 Sass 设置的，因此仍然支持 Sass 自定义。

  --#{$prefix}card-spacer-y: #{$card-spacer-y};
  --#{$prefix}card-spacer-x: #{$card-spacer-x};
  --#{$prefix}card-title-spacer-y: #{$card-title-spacer-y};
