- 你好，在添加了背景色的导航栏后，我的h1是没有出现。我正试图将我的h1-h6标签居中网站，这样我就可以将其设置为不同的字体类型，但当我添加h1标记带有，或者h1标记仍然没有出现

<!---SHOPPING ICON--->我认为你想在走路之前先跑。学习新事物是件好事，但要循序渐进。
首先试着了解网页是什么以及它是如何制作的。
尝试理解DOM DOM基础
然后是不同的标签(div、span、p、h1、h2、h3、em、style、script、head、body、html(
然后使用<a href="一些网站地址.com">酷网站老兄<>
表单对初学者来说非常困难，因为它们不仅仅涉及前端代码(HTML、CSS、JavaScript(，因为现在你正在编写后端代码，如果你有服务器和数据库的话，它可以与服务器和数据库对话！
先是基础知识，然后是更复杂的主题。
我已经更新了你的代码，但不确定它是否会给你想要的。
顺便说一句，网页中只有一对html、head和body标签。
