Bootstrap 4图像缩略图类

问题描述 投票：5回答：2

我使用bootstrap 3.3.7获得了以下HTML代码，使用缩略图类可以调整图像大小并完美地适应网格。

 <!DOCTYPE html>
 <html lang="en">
 <head>
   <meta charset="utf-8">
   <title>Project</title>
   <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
 </head>

<div class="container">
  <h2>Pictures of Coffee</h2>
  <div class="row">
 <div class="col-lg-4 col-xs-6 thumbnail"><img src="https://d2lm6fxwu08ot6.cloudfront.net/img-thumbs/960w/04LDEYRW59.jpg" alt=""></div>
    <div class="col-lg-4 col-xs-6 thumbnail"><img  src="https://d2lm6fxwu08ot6.cloudfront.net/img-thumbs/960w/90V03Q5Y60.jpg" alt=""></div>
    <div class="col-lg-4 col-xs-6 thumbnail"><img  src="https://d2lm6fxwu08ot6.cloudfront.net/img-thumbs/960w/O83SF2RB6D.jpg" alt=""></div>
    <div class="col-lg-4 col-xs-6 thumbnail"><img  src="https://d2lm6fxwu08ot6.cloudfront.net/img-thumbs/960w/5JVPSVP7EI.jpg" alt=""></div>
    <div class="col-lg-4 col-xs-6 thumbnail"><img  src="https://d2lm6fxwu08ot6.cloudfront.net/img-thumbs/960w/C5Y10KIIHA.jpg" alt=""></div>
    <div class="col-lg-4 col-xs-6 thumbnail"><img  src="https://d2lm6fxwu08ot6.cloudfront.net/img-thumbs/960w/YSSFRY5B25.jpg" alt=""></div> 
  </div>
</div>

 </body>
 </html>

但是，在引导程序4.0中似乎不存在缩略图类https://getbootstrap.com/docs/4.0/layout/grid/为了模拟问题，您可以尝试使用以下内容替换html链接rel

 <link rel="stylesheet"
 href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"
 integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm"
 crossorigin="anonymous">

您可以看到图像将不在某些地方，我想知道在4.0中实现相同结果的类似类是什么。或者我必须使用bootstrap 3.3.7？

根据docs v4，你正在寻找img-thumbnail（应该用img标签代替col-*-*）

笔记：

  • 在v4中，col-xs被col-取代
  • 我添加了img-fluid实用程序类，以使图像响应

在Bootstrap 4中，您可以执行以下操作。

对于列col-xs-不再存在，请替换为col-。默认值为xs。

对于缩略图，您可以在img-thumbnail元素上使用img类，而不是在div元素上使用。

此外，要在每个列和行上实现0填充，您可以通过添加自定义样式规则来覆盖Bootstrap的填充。

    .row > .col-lg-4,
       .col-6 {
               padding: 0;
       }

生成的Bootstrap 4文件如下：

    <!DOCTYPE html>
