Question

我试图列出一些图片，并且对于每张图片我想要一个标题，有一些细节，让我们说标题，现在的问题是标题的宽度是相对于正常的父div，但我希望它相对于图像宽度，但由于我在img上有类img-responsive，我不知道如何实现这一点。也许你们可以帮助我。

以下是一个实例：http://jsbin.com/cudugize/1/edit?html,css,output

这是代码

HTML

  <div class="col-sm-3 col-xs-6 col-md-2 col-lg-3">
  <div class="thumbnail">
  <a href="url"><img width="139" height="161" src="http://lorempixel.com/139/161/nightlife/" class="img-responsive" alt="..."></a>
  <div class="caption img-responsive">
  <h4 class="text-center"><a href="url" title="title" class="homepage anchorhead text-uppercase">Nice title</a></h4>
  <p class="text-center"><a href="#" class="homepage city text-uppercase"><span class="glyphicon glyphicon-globe"></span> usa</a></p>
  </div>
  </div>

  <div class="thumbnail">
  <a href="url"><img width="139" height="161" src="http://lorempixel.com/139/161/nightlife/" class="img-responsive" alt="..."></a>
  <div class="caption img-responsive">
  <h4 class="text-center"><a href="url" title="title" class="homepage anchorhead text-uppercase">Nice title</a></h4>
  <p class="text-center"><a href="#" class="homepage city text-uppercase"><span class="glyphicon glyphicon-globe"></span> usa</a></p>
  </div>
  </div>

  </div>

CSS

Aditional bootstrap core css

.thumbnail{
position: relative;
width: 100%;
border: none !important;
}
.thumbnail .caption{
  position: absolute;
bottom: 0px;
background: rgba(0,0,0,0.50);
width: 100%;
padding: 0px !important;
}

Answer 2

这个CSS应该可以解决问题：

.thumbnail {
  display: inline-block;
  position: relative;
  border: none !important;
  padding: 0;
}
.thumbnail .caption{
  position: absolute;
  bottom: 0px;
  background: rgba(0,0,0,0.50);
  width: 100%;
  padding: 0px !important;
}

Bootstrap对齐标题相对于图像宽度而不是容器
