html - 悬停时将背景图像更改为颜色

Question

当鼠标悬停在 div 上时，我试图将 div 的背景从图像更改为颜色。我几乎完成了它，但颜色也覆盖了 div 内的文本。

HTML:

<div>
    <h3>LIPSUM DOLORES DILORES DUM DUM</h3>
    <p>Lorem Ipsum is simply dummy text of the printing and typesetting 
    industry. Lorem Ipsum has been the industry's standard dummy text ever
    since the 1500s, when an unknown printer took a galley of type and
    scrambled it to make a type specimen book. It has survived not only five
    centuries, but also the leap into electronic typesetting, remaining 
    essentially unchanged.</p>
</div>

CSS:

div {
  background-image: url("https://static.pexels.com/photos/127028/pexels-photo-127028.jpeg");
  background-size: cover;
  width: 300px;
  height: 300px;
}

div:before {
  content: "";
  position: absolute;
  top: 0;
  left: 0;
  width: 300px;
  height: 300px;
  background: rgba(0, 0, 0, 0.6);
  opacity: 0;
  transition: all 0.8s;
}

div:hover:before {
  opacity: 1;
  background: rgba(0, 0, 0, 1);
  transition: all 0.8s;
}

div h3,
div p,
body {
  margin: 0;
  padding: 0;
}

div h3,
div p {
  color: red;
  z-index: 1000;
}

你可以这样做

.outer {
  background-image: url("https://static.pexels.com/photos/127028/pexels-photo-127028.jpeg");
  background-size: cover;
  width: 300px;
  height: 300px;
}

.outer:before {
  content: "";
  position: absolute;
  top: 0;
  left: 0;
  width: 300px;
  height: 300px;
  background-color: rgba(0, 0, 0, 0.6);
  opacity: 0;
  transition: all 0.8s;
}

.outer:hover:before {
  opacity: 1;
 
}
.inner{
  position: relative;
}

div h3,
div p,
body {
  margin: 0;
  padding: 0;
}

div h3,
div p {
  color: red;
  z-index: 1000;
}

<div class="outer">
  <div class="inner">
   <h3>

  Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
