所以我尝试使用XHTML，因为我想从PHP学习中休息一下。我已经知道HTML、CSS和JavaScript。但我只是想尝试一下其他一些语言，比如SCSS。所以无论如何，我用XHTML运行我的个网站，但是由于某些原因，<h1>标记不能工作，只能像加载常规页面一样加载它。总之，这里是源代码:

<?xml version="1.0" encoding="iso-8859-1"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"

"https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xml:lang="en" lang="en" xmlns="https://www.w3.org/1999/xhtml">
<head>
  <title>XHTML not HTML</title>
</head>
<body>
  <h1>XHTML not HTML</h1>
  <p>XHTML has always existed alongside html as an alternative for those who want the best out of both XML and HTML. So far XHTML5 is under way so lots of XHTML is more similar to HTML4 than HTML5. That said it is better than HTML, just until XHTML5 comes out nobody will be using it. If you know html already you already know most of XHTML. And will not find it difficult to learn XML. If you know CSS, you will not find it very difficult to learn SCSS. and If you know JavaScript, you will have some good background knowledge, that will make it easier to learn TypeScript, and CoffeeScript.</p>
