响应式悬停以响应图像

Question

如何做响应式悬停？

这是一个很好的悬停示例，它非常适合我的屏幕尺寸，这很糟糕，没有响应的悬停示例

这是我的代码

HTML

  <div class="product-img-list">
    <%= link_to product_path(product), class: 'product_link' do %>
    <%= image_tag(product.image_url, class: "img-responsive",  size: "300x250") %>
    <% end %>
    <span class="product-img-text"><span>code</span></span>
  </div>

CSS

span.product-img-text {
  background: rgba(0,0,0,0.5);
  color: white;
  cursor: pointer;
  display: table;
  height: 80px;
  left: 15px;
  position: absolute;
  top: 230px;
  width: 291px;
  opacity: 0;
  -webkit-transition: opacity 500ms;
  -moz-transition: opacity 500ms;
  -o-transition: opacity 500ms;
  transition: opacity 500ms;
}

.product-img-list:hover span.product-img-text {
  opacity: 1;
}

span.product-img-text span {
  display: table-cell;
  text-align: center;
  vertical-align: middle;
}

.img-responsive {
  list-style-type: none;
  margin: 0;
  padding: 0;
  text-align: center;
}

.product-img-list.img-responsive {
  display: inline-block;
  margin: 0 1em 1em 0;
  position: relative;
}

感谢您的帮助

我想说你必须让 int roomIs = 0; Console.WriteLine("Hello World. Type /Help for help or /Play to play!"); roomIs = 1; var Enter = default(string); do { Enter = Console.ReadLine(); switch (Enter) { case ("/Help"): Console.Clear(); Console.WriteLine("Welcome to the help room, type /Return to return to your last room!"); break; case ("/Return"): if (roomIs == 1) { Console.Clear(); Console.WriteLine("Hello World. Type /Help for help or /Play to play!"); } break; } } while (!string.IsNullOrEmpty(Enter)); 做出回应（而不是使用硬编码维度）

类似于以下内容

.product-img-text

如果不是span.product-img-text { background: rgba(0,0,0,0.5); color: white; cursor: pointer; display: table; position: absolute; height: 25%; /*assuming text is not that much*/ left: 1em; /*to account for margin*/ right:1em /*to account for margin*/ bottom: 0; /*add it to bottom of image*/ opacity: 0; -webkit-transition: opacity 500ms; -moz-transition: opacity 500ms; -o-transition: opacity 500ms; transition: opacity 500ms; } ，则必须将其.product-img-list定位。
