Bootstrap4 卡片
简单的卡片
我们可以通过 Bootstrap4 的 .card 与 .card-body 类来创建一个简单的卡片，实例如下:
Bootstrap4 的卡片类似 Bootstrap 3 中的面板、图片缩略图、well。
头部和底部
.card-header类用于创建卡片的头部样式， .card-footer 类用于创建卡片的底部样式：
实例
< div class = " card " > < div class = " card-header " > 头部 </ div > < div class = " card-body " > 内容 </ div > < div class = " card-footer " > 底部 </ div > </ div >

标题、文本和链接
我们可以在头部元素上使用 .card-title 类来设置卡片的标题 。 .card-text 类用于设置卡片正文的内容。 .card-link 类用于给链接设置颜色。
实例
< div class = " card " > < div class = " card-body " > < h4 class = " card-title " > Card title </ h4 > < p class = " card-text " > Some example text. Some example text. </ p > < a href = " # " class = " card-link " > Card link </ a > < a href = " # " class = " card-link " > Another link </ a > </ div > </ div >

图片卡片
我们可以给 <img> 添加 .card-image-top（图片在文字上方） 或 .card-image-bottom（图片在文字下方 来设置图片卡片：
实例
< div class = " card " style = " width:400px " > < img class = " card-img-top " src = " img_avatar1.png " alt = " Card image " > < div class = " card-body " > < h4 class = " card-title " > John Doe </ h4 > < p class = " card-text " > Some example text. </ p > < a href = " # " class = " btn btn-primary " > See Profile </ a > </ div > </ div >

如果图片要设置为背景，可以使用 .card-img-overlay 类:
实例
< div class = " card " style = " width:500px " > < img class = " card-img-top " src = " img_avatar1.png " alt = " Card image " > < div class = " card-img-overlay " > < h4 class = " card-title " > John Doe </ h4 > < p class = " card-text " > Some example text. </ p > < a href = " # " class = " btn btn-primary " > See Profile </ a > </ div > </ div >
