Define custom tags by specifying the name of the html namespace; some of the default tags p div, etc. are under the default namespace of html. Custom tags can be placed under a custom namespace, which can be specified through xmlns: namespace name. Custom tags need to have a namespace name, and use "namespace name: tag name" when setting styles.

<!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd>
<html xmlns:ownhtml>
<head>
    <meta charset="UTF-8">
    <title>Document</title>
    <style>
        ownhtml\:customdiv{
            font-size: .36rem;
            font-weight: bold;
            color:red;
        }
        p{
            color: green;
        }
    </style>
</head>
 <body>
  <!--
  通过指定html命名空间的名字来定义自定义标签;默认的一些标签p div等都在html默认的命名空间下。而自定义的标签可以放在自定义的命名空间下,可通过xmlns:命名空间名 来指定,而自定义标签需要带命名空间名,而在设置样式的时候使用 " 命名空间名\:标签名  "
  -->
    <ownhtml:customdiv class="custom">this is a custom element!</ownhtml:customdiv>
 
    <p>this is normal text</p>
</body>
</html>
