如何使用CSS将文本放置在图像的中心
要定位文本以使图像居中，请使用CSS中的transform属性。您可以尝试对图像的居中文本运行以下代码
示例
<!DOCTYPE html>
<html>
<head>
<style>
.container {
position: relative;
}
.topleft {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
font-size: 18px;
}
img {
width: 100%;
height: auto;
opacity: 0.3;
}
</style>
</head>
<body>
<h2>Image Text</h2>
<p>Add some text to an image in the center of an image:</p>
<div class = "container">
<img src = "trolltunga.jpg" alt = "Norway" width = "1000" height = "300">
<div class = "topleft">Center</div>
</div>
</body>
</html>
