我试图将一个自制的字幕集中在图像上,但它的工作效果不太好。我不确定我做错了什么,但这里有一个小提示,显示我正在做的事情:https://jsfiddle.net/efvL28o0/。
HTML
<div class= "container-fluid">
<div class="row">
<div class="col-md-3">
<a href="" class="rel-tile" >
<img src="http://via.placeholder.com/1000x500" width="100%">
<span class="btn-center text-center caption-custom">About Me</span>
</a>
</div>
<div class="col-md-3">
<a href="" class="rel-tile">
<img src="http://via.placeholder.com/1000x500" alt="" width="100%">
<span class="btn-center text-center">Lineage</span>
</a>
</div>
<div class="col-md-3">
<a href="" class="rel-tile">
<img src="http://via.placeholder.com/1000x500" alt="" width="100%">
<span class="btn-center text-center">Contact Me</span>
</a>
</div>
<div class="col-md-3">
<a href="" class="rel-tile">
<img src="http://via.placeholder.com/1000x500" alt="" width="100%">
<span class="btn-center text-center">Gallery</span>
</a>
</div>
</div>
</div>
CSS
.rel-tile {
position: relative;
}
.btn-center {
position: absolute;
top: 45%;
opacity: 0.6;
left:45%;
background-color: black;
color: white;
text-decoration: none;
}
理想情况下,无论我为btn-center设置的大小,它都会完全浮在中间。
谢谢!

将.btn-center
样式更改为:
.btn-center {
position: absolute;
top: 50%;
opacity: 0.6;
left:50%;
background-color: black;
color: white;
text-decoration: none;
transform: translate(-50%, -50%);
}
这里的主要部分是transform: translate(-50%, -50%);
它是常见的对中技术之一。
