卡片（Card）
Bootstrap的卡提供了一個靈活的、可擴展的內容容器，其中包含多種變體和選項。
關于
卡片是一個有彈性且可擴展的內容容器。它包含了頁首和頁尾的選項、多樣化的內容、上下文的背景顏色以及強大的展示選項。如果你很熟悉Bootstrap 3，那卡片將取代舊有的panel，well和thumbnail。與那些元件類似的功能已經都整合到卡片內了
例子
卡片被設計成盡可能的少用一些標記和樣式，但它仍然可以提供許多的控件和自定義。使用flexbox構建，它們可以更方便的對齊，并與其它的Bootstrap元件良好混合。預設中它并沒有margin，所以可以依需求加入spacing通用類別。
以下是一個具有混合內容和固定寬度的基本卡片示例。卡片如果沒有固定的寬度，那么它們將自然填充其父元素的全部寬度。這可以透過我們的各種縮放選項輕松調整。
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>內容類型
卡片支持各種內容，包含圖片、文字、清單群組、連接等。以下為卡片支持的示例。
主體
卡片的構造塊是.card-body。當你需要卡片中的填充部分時就使用它。
<div class="card">
<div class="card-body">
This is some text within a card body.
</div>
</div>標題、文本和鏈接
在<h*>標簽中添加.card-title以使用卡片標題。同樣的，在a標簽中加入.card-link并使連接彼此相鄰。
在<h*>標簽中加入.card-subtitle以使用副標題。如果.card-title以及.card-subtitle元件被放在card-body里面，它們將會對齊良好。

<a href="#" class="card-link">Card link</a>
<a href="#" class="card-link">Another link</a>
</div>
</div>圖片
設定.card-img-top將會把圖片放在卡片的頂部。使用.card-text可以將文字內容可以添加到卡片中。.card-text中的文本也可以用標準的HTML標簽設計樣式。

</div>圖像
卡片包含一些用來處理圖片的選項。選擇在卡片的任一端附加“image caps”，用卡片內容覆蓋圖片，或者只是將圖象嵌入到卡中。
Image caps
與頁首或頁尾相似，卡片可以包含頂部或是底部的“Image caps”，即圖片是位于卡片的頂部或是底部。

將圖片轉換為卡片背景，并疊加卡片的文字。根據圖片，你可以選擇是否需要額外的樣式或通用類別。

</div>水平
結合使用網格以及通用類別，可以讓卡片以行動友善且響應式的方法呈現水平狀態。在下面的示例中，我們使用.g-0移除網格的間隙，并使用.col-md-*類別讓卡片在md斷點之后呈現水平。根據卡片內容，將可能會需要一些額外的調整。

</div>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.
邊框
使用邊框通用類別來改變卡片的border-color。你也能在.card父層設置.text-{color}類別，或是如以下示例設置在卡片內容的子集當中。

</div>卡片布局
除了對卡片內容進行樣式設計以外，Bootstrap還提供一些用于卡片排版的選項。目前為止，這些排版選項還不是響應式的。
卡片組
使用卡片群組將一系列卡片呈現為具有等寬、高字段的單一、連接元素。卡片群組由堆疊開始，并透過display: flex；從sm的斷點后開始以統一的尺寸相連接。

使用Bootstrap的網格系統以及.row-cols類別來控制每行應該顯示多少網格欄（用于包裝卡片）。以下面的例子來說，.row-cols-1將卡片布置為一欄，而.row-cols-md-2將會從md的斷點后開始將四個卡片設置為等寬、跨多行。

</div>如果需要相等高度時，把.h-100添加于卡片上。如果希望卡片預設就是等高，可以在Sass設置$card-height: 100%。

</div>Masonry
在v4版本我們僅使用CSS技術來模仿Masonry字段效果，但這樣的技術帶來了許多不愉快的副作用。如果你想要在v5中使用這種排版，則可以使用Masonry的插件。Mansory并沒有被包括于Bootstrap，但我們有制作一個demo示例來幫助你開始使用它。
