Question

我有4张照片的网格布局，我需要将它们设置为悬停时要更改。

我可以使用'img：hover'和'position：absolute;'一张图像来做到这一点。但是，对于多张图片，绝对定位会弄乱布局。

* {
  box-sizing: border-box;
}

.column {
  float: left;
  width: 50%;
  padding: 5px;
}

.row::after {
  content: "";
  clear: both;
  display: table;
}

<div class="row">
  <div class="column">
    <img src="https://helpx.adobe.com/content/dam/help/en/stock/how-to/visual-reverse-image-search/jcr_content/main-pars/image/visual-reverse-image-search-v2_intro.jpg" alt="Snow" style="width:100%">
  </div>
  <div class="column">
    <img src="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSV7Xfy9xsIHJKQDzyNeuADyO-dTfLioo221t2-7m8ABCWDiaJKTQ" alt="Forest" style="width:100%">
  </div>
</div>
<div class="row">
  <div class="column">
    <img src="https://helpx.adobe.com/content/dam/help/en/stock/how-to/visual-reverse-image-search/jcr_content/main-pars/image/visual-reverse-image-search-v2_intro.jpg" alt="Snow" style="width:100%">

  </div>
</div>

这是我到目前为止的代码，我尝试在CSS中添加background（url ...）无济于事。

任何帮助/指导将不胜感激，非常感谢！

您可以使用CSS使用叠加层。请检查一下。.它会为您工作

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">
<style>
.container {
  position: relative;
  width: 50%;
}

.image {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  height: 100%;
  width: 100%;
  opacity: 0;
  transition: .5s ease;
  background-color: #008CBA;
}

.container:hover .overlay {
  opacity: 1;
}

.text {
  color: white;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);

Answer 3

解决方案是添加上面Lalji建议的代码，以便将样式相应地应用于图像。
