我将悬停标题的教程转换为bootstrap。问题是网格样式组合是响应式的，我似乎无法获得响应的标题。我尝试将高度和宽度设置为100％，但这不起作用？有什么提示吗？

Velibor Nikolic 你好。
您在div中使用ul > li这可能不是一个好主意看看 link here 。

尝试使用标题执行此类操作。对于工作示例，请查看此 Fiddle 。

这完全响应，包括图像和标题我使用class的引导col-xs-12作为宽度，标题class使用height:100%。

我减少了一些classes并将阴影背景添加到标题class，不需要模糊class。

以下是带有标题的一个图像块的示例。

<div class="col-sm-4 col-xs-12 clear-L-R">
     <img src="http://lorempixel.com/640/640/nature" class="img-responsive clear-L-R" alt="">
     <div class="col-xs-12 caption caption-text">
          <h1>Amazing Caption</h1>
          <p>Whatever It Is - Always Awesome</p>
      </div>
</div>

Bootstrap使图像悬停字幕响应
