卡片

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

关于

卡片是一个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、孔和缩略图。与这些组件类似的功能可用作卡的修饰符类。

示例

卡片的构建具有尽可能少的标记和样式，但仍然设法提供大量的控制和自定义。它们采用弹性盒构建，易于对齐，并可与其他Bootstrap组件很好地混合。默认情况下，它们没有margin，因此根据需要使用间距实用程序。

下面是具有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，因此它们自然会填充其父元素的整个宽度。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，包括图像、文本、列表组、链接等。以下是支持的内容示例。

主体（Body）

卡的构建块是 .card-body。每当您需要在卡片中填充部分时使用它。

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（Titles, text, and links）

卡片标题是通过将.card-title添加到<h*>标签来使用的。以同样的方式，通过将.card-link添加到<a> 标签来添加链接并放置在彼此相邻的位置。

副标题是通过在<h*> 标签中添加.card-subtitle来使用的。如果将 .card-title和.card-subtitle项放在.card-body项中，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（Images）

.card-img-top将图像放置在卡片的顶部。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标记设置样式。

调整尺寸大小（Sizing）

卡片假定没有特定的width开始，因此除非另有说明，否则它们将是 100% 宽的。您可以根据需要使用自定义 CSS、网格类、网格 Sass mixins 或实用程序来更改此设置。

使用网格标记

使用网格，根据需要将卡片包装在列和行中。

水平（Horizontal）

使用网格和实用程序类的组合，可以以移动友好和响应的方式水平制作卡片。在下面的示例中，我们删除了带有 .g-0的网格槽，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。

卡片布局

除了设置卡片中内容的样式外，Bootstrap 还包括一些用于布置一系列卡片的选项。目前，这些布局选项尚未响应。

卡片组

使用卡片组将卡片呈现为具有相等宽度和高度列的单个附加元素。卡片组从堆叠开始，并使用display: flex; 以从sm断点开始连接统一尺寸

网格卡片

使用 Bootstrap 网格系统及其 .row-cols 类来控制每行显示多少网格列（环绕在卡片上）。例如，此处是 .row-cols-1将卡片布置在一列上，.row-cols-md-2将四张卡片拆分为多行的宽度相等，从中等断点开始。

当您需要相同的高度时，请在卡片上添加.h-100。如果您默认想要相等的高度，您可以在 Sass 中设置$card-height: 100%。

砌体（Masonry）

在v4中，我们使用了一种纯CSS技术来模仿类似Masonry的列的行为，但是这种技术带来了许多令人不快的副作用。如果你想在v5中拥有这种类型的布局，你可以使用砌体插件。砌体不包含在Bootstrap中，但我们做了一个演示示例来帮助你入门。

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。CSS 变量的值是通过 Sass 设置的，因此仍然支持 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};
