Html CSS图像标题悬停，带过渡

我一直在尝试实现类似于此的CSS图像悬停。我无法将悬停包含到我的图像中

很重要的一点是我要使用ZURB基金会和“大块网格”类。干杯

我的HTML：

<div class="recent-work">
  <div class="row">
    <div class="large-12 columns">
      <ul class="large-block-grid-2">
        <li>
         <a href="#">
           <div class="caption"><span>First Image Hover</span></div>
           <img src="http://hhhhold.com/577x577">
         </a>
         </li>
         <li>
          <a href="#">
            <div class="caption"><span>Second Image Hover</span></div>
            <img src="http://hhhhold.com/577x577">
          </a>
         </li>
      </ul>
    </div>
  </div>
</div><!-- End recent-work -->

这里有一个

此解决方案在大屏幕上正常工作，但在较小屏幕（iPhone和Galaxy）上，滚动比图像大。无论如何，关于如何修复它的建议？尝试设置

img{width:400px；height:400px；}

Nope运气不好，它会损坏到图像的右侧。

.recent-work {
  margin: 0 0 50px;
}

// Img hovers

.caption span {
  top: 50%;

ul.large-block-grid-2 .caption {
