## 使用文本对齐中心居中图像
|
||
|
|
|
||
|
|
`<img>`元素是内联元素（ `inline-block`显示值）。它可以通过添加`text-align: center;`轻松居中`text-align: center;`父元素的CSS属性 包含它。
|
||
|
|
|
||
|
|
使用`text-align: center;`来居中图像`text-align: center;`您必须将`<img>`放在块级元素（如`div` 。 由于`text-align`属性仅适用于块级元素，因此请放置`text-align: center;`在包装块级元素上实现水平居中的`<img>` 。

|
|
<!DOCTYPE html>
|
||
|
|
<html>
|
||
|
|
<head>

|
.img-container {
|
||
|
|
text-align: center;
|
||
|
|
}
|
||
|
|
</style>
|
||
|
|
</head>
|
||
|
|
<body>
|
||
|
|
<div class="img-container"> <!-- Block parent element -->
|
||
|
|
<img src="user.png" alt="John Doe">
|
||
|
|
</div>
|
||

|
</body>
|
||
|
|
</html>
|
