我必须在 html 中创建一个图像,并添加 css 悬停以在用户将鼠标悬停在图像上方时显示一个 div。
我尝试将 image:hover
添加到我的 css 中,但它似乎不起作用,我不明白为什么。
这是我的 html
<div class="col-lg-6 col-sm-6">
<div class="image">
<img class="img-fluid" src="images/example.png" alt="Website" />
<div class="overlay">
<a class="portfolio-box" href="http://example.com" target="_blank">
<div class="portfolio-box-caption">
<div class="project-name">Example</div>
</div>
</a>
</div>
</div>
</div>
这是我的 css
.overlay {
display: none;
}
.image {
position: relative;
display: inline-block;
}
.image:hover .overlay {
position: absolute;
display: block;
display: flex;
align-items: center;
justify-content: center;
flex-direction: column;
width: 100%;
height: 100%;
bottom: 0;
text-align: center;
opacity: 0;
color: #fff;
background: #f86d27;
transition: opacity 0.25s ease;
text-align: center;
}

正如在评论中提到的,您必须删除 opacity:0;
。它将使您的悬停放置样式不可见。
.overlay {
display: none;
}
.image {
position: relative;
display: inline-block;
}
.image:hover .overlay {
position: absolute;
display: block;
display: flex;
align-items: center;
justify-content: center;
flex-direction: column;
width: 100%;
height: 100%;
bottom: 0;
text-align: center;
color: #fff;
background: #f86d27;
transition: opacity 0.25s ease;
text-align: center;
}
