Bootstrap是一個流行的前端框架，它提供了許多用于快速構(gòu)建響應(yīng)式網(wǎng)頁的工具和組件。除了對卡片內(nèi)容進(jìn)行樣式設(shè)計外，Bootstrap還提供了一些用于卡片排版的選項。包括排版組、網(wǎng)絡(luò)卡片、Masonry等。
一、卡片組
使用卡片群組將一系列卡片呈現(xiàn)為具有等寬、高字段的單一、連接元素?？ㄆ航M由堆疊開始，并透過display: flex；從sm的斷點后開始以統(tǒng)一的尺寸相連接。
<div class="card-group"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p> </div> </div> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p> <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p> </div> </div> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p> <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p> </div> </div> </div>
當(dāng)在卡片群組使用頁尾，它們的內(nèi)容將會自動對齊。
<div class="card-group"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> <div class="card-footer"> <small class="text-muted">Last updated 3 mins ago</small> </div> </div> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p> </div> <div class="card-footer"> <small class="text-muted">Last updated 3 mins ago</small> </div> </div> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p> </div> <div class="card-footer"> <small class="text-muted">Last updated 3 mins ago</small> </div> </div> </div>
二、網(wǎng)格卡片
使用Bootstrap的網(wǎng)格系統(tǒng)以及.row-cols類別來控制每行應(yīng)該顯示多少網(wǎng)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(shè)置為等寬、跨多行。
<div class="row row-cols-1 row-cols-md-2 g-4"> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content.</p> </div> </div> </div> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> </div>
更改為.row-cols-3，則會看到第四張卡片被換行。
<div class="row row-cols-1 row-cols-md-3 g-4"> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content.</p> </div> </div> </div> <div class="col"> <div class="card"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> </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(yù)設(shè)就是等高，可以在Sass設(shè)置$card-height: 100%。
<div class="row row-cols-1 row-cols-md-3 g-4"> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a short card.</p> </div> </div> </div> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content.</p> </div> </div> </div> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a longer card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> </div> </div> </div>
如同卡片群組，卡片頁尾也會自動對齊。
<div class="row row-cols-1 row-cols-md-3 g-4"> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p> </div> <div class="card-footer"> <small class="text-muted">Last updated 3 mins ago</small> </div> </div> </div> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p> </div> <div class="card-footer"> <small class="text-muted">Last updated 3 mins ago</small> </div> </div> </div> <div class="col"> <div class="card h-100"> <img src="..." class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title">Card title</h5> <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p> </div> <div class="card-footer"> <small class="text-muted">Last updated 3 mins ago</small> </div> </div> </div> </div>
三、Masonry
在v4版本我們僅使用CSS技術(shù)來模仿Masonry字段效果，但這樣的技術(shù)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。
