将背景图像更改为悬停时的颜色

Question

我试图将鼠标悬停在图像上时将图像的背景改为颜色。我设法几乎完成了它，但颜色也覆盖了div内的文字。

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; 
}

，你可以做这样的

.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> 
 
    LIPSUM DOLORES DILORES DUM DUM 
 
    </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.
