  • 您好,在添加了背景色的导航栏后,我的h1没有显示。我试图将我的h1-h6标签居中在我的网站的中心,这样我就可以将其样式设置为不同的字体类型,但当我添加了带有、或的h1标签时,h1标签仍然没有显示。

我认为你是在学走路之前就想跑。学习新东西是好的,但要一步一步来。
首先试着了解什么是网页,它是如何制作的。
尝试了解DOM DOM basics
然后是不同的标签(div、span、p、h1、h2、h3、em、样式、脚本、head、body、html)
〈/〉然后使用酷网站导航花花公子!
表单对于初学者来说是非常困难的,因为它们涉及的不仅仅是前端代码(HTML、CSS、JavaScript),因为现在你正在编写与服务器和数据库(如果你有)对话的后端代码!
首先是基础知识,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予你你想要的。

顺便说一句,您的网页中只有1对html、head和body标签。
