使用HTML中的dir属性来设置一个从右到左的段落。将rtl值添加到dir属性中，使文本从右到左排列。
您可以尝试运行以下代码来实现dir 属性：
<!DOCTYPE html> <html> <body> <p dir="rtl">This is demo paragraph. This is demo paragraph. This is demo paragraph. This is demo paragraph. This is demo paragraph. This is demo paragraph. This is demo paragraph.</p> </body> </html>
