I introduced a demo.css into an html page, everything else is normal, but the align attribute of the h4 tag cannot be displayed correctly. Is it because align cannot be written in the link expression? There is no problem if you write it inline.
The code is as follows:
This is a few lines of code for the html page
<h1 style="color:blue">前端工程师：JavaScript，PHP，CSS！<br/>
</h1>
<h2 id="测试CSS的四种形式">2.测试CSS的四种形式</h2>
<hr/>
<h3 id="css的导入式">3.css的导入式</h3>
<br/>
<h4 id="这是CSS的链接式">4.这是CSS的链接式</h4>这是CSS文件：
h3{ color: green;
}
h4{
color: pink; align:center;
}
.my{
align:right; color: blue;
}#xzq{
align:left;color: red;
}
.php{color: red;}Another screenshot

It should be text-align:center; but align is not possible
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title></title>
<style media="screen">
*{
padding: 0;
margin: 0;
}
h4{
background-color: rgb(222, 93, 174);
color: rgb(194, 238, 7);
text-align: center;
}
</style>
</head>
<body>
<h4 id="这是CSS链接式">这是CSS链接式</h4>
</body>
</html>But be careful when writing this way, all
are added For this attribute, it is best to fill in an id or class for this attribute and modify the alignment of the text under the h4 tag separately.
text-align should be the attribute you are looking for
