XML - 管理数据交换/CSS/答案

练习 1

这里是一种方法

为了能够将外部样式表与 XML 文档连接，您需要在文档开头，在
<?xml-stylesheet type="text/css" href="excercise1.css"?>
下方写入
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

像这样

<?xml version="1.0" encoding="UTF-8"  standalone="yes"?>
<?xml-stylesheet type="text/css" href="exercise1.css"?>
