Question

我在井内有一个image。

当悬停图像/井时，叠加信息显示（目前这是正确的）。

覆盖层应覆盖图像所在的整个孔（灰色部分）。 product-title位于图像/孔下方，与井分开。

因此，当悬停时product-title不应受到影响（实际上应该是红色background，文字字体color应该变为白色）。

现在如何实现包括product-title在内的整个事物在悬停时变成灰色？

所以实际上现在一切都很好，只有当徘徊product-title div应该有自己的风格而不是＆＃34;隐藏＆＃34;通过灰色叠加。

Answer 1

您需要在父position:relative中设置.product-detailsmas，否则position:absolute设置为原样，会使元素脱离流，而不是父元素。< / p>

并通过将product-titlesidebar

作为兄弟来更改.product-detailsmas

注意，因为您使用的是width/height:100% + padding，您需要box-sizing才能避免使用滚动条

＆＃13;

.product-detailsmas {
  position: relative
}
.product-detailsmas .overlay {
  box-sizing: border-box;
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  opacity: 0;
  border-radius: 0;
  background: #F7F7F7;
  color: blue;
  text-align: center;
  padding: 10px;
  border-top: 1px solid #A10000;
  /* vertical-align: middle; */
  -webkit-transition: opacity 500ms;
  -moz-transition: opacity 500ms;
  -o-transition: opacity 500ms;
  transition: opacity 500ms;
}
.product-detailsmas {
  background-color: #E6E6E6;
  text-align: center;
}
.product-detailsmas:hover .overlay {
  opacity: 1;
}
.well.sb .product-titlesidebar {
  font-size: 13px;
  font-family: 'Montserrat', sans-serif;
  color: #444;
  font-weight: 700;
  line-height: 1.25em;
  margin: 5px;
}

Answer 2

ADD ：position: relative;到.product-detailsmas CSS。

这会将绝对定位元素限制为父元素。

删除：.product-detailsmas .overlay上的填充 - 这会导致叠加层大于父级。

.product-detailsmas .overlay {
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    opacity: 0;
    border-radius: 0;
    background: #F7F7F7;
    color: blue;
    text-align: center;
    border-top: 1px solid #A10000;
    /* vertical-align: middle; */
    -webkit-transition: opacity 500ms;
    -moz-transition: opacity 500ms;
    -o-transition: opacity 500ms;
    transition: opacity 500ms;
}

.product-detailsmas {
    background-color: #E6E6E6;
    text-align: center;
  position: relative;
}

.product-detailsmas:hover .overlay {
    opacity: 1;
}

.well.sb .product-titlesidebar {
    font-size: 13px;
    font-family: 'Montserrat',sans-serif;
    color: #444;
    font-weight: 700;
    line-height: 1.25em;
    margin: 5px;
}

<div>
        <a href="#" target="_blank">
        <div class="product-detailsmas">
            <div class="image-video-linksidebar">

我知道它在技术上还可以，但我个人不在锚标记内加载一堆独立的div。

覆盖不包括div
