如何使用html和css在淡入覆盖图中居中显示文本？
如何使用html和css在淡入覆盖图中居中显示文本？
提问于 2018-07-04 02:40:42
我偶然发现了这个tutorial，它为我提供了有关如何创建图像的说明，当图像悬停在图像上时，该图像将转换为文本
但是，我的文本对于图像来说太大了，所以我试图减少悬停覆盖的边距。
我更改了.text类，使顶部和左侧的值为20%，还更改了transform属性和ms-transform属性。但现在的问题是，文本不再居中
请参阅下面的代码和codepen here
<!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: 20%;
left: 20%;
transform: translate(-20%, -20%);
-ms-transform: translate(-20%, -20%);
text-align: center;
}
</style>
</head>

<div class="text">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.
Contrary to popular belief, Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32.
