<html> tag, used to indicate the beginning and end of the web page. Within the
<html> tag, there are usually two important sub-tags:
<head> and
<body>.
<ul>
<li>
<head> Tag: The content inside it will not be displayed directly in the browser, but is mainly used to provide metadata for the page. It can include
<title> tags (used to set the title of the web page) and
<meta> tags (used to set the keywords, description and other information of the web page), etc.
<li>
<body> Tags: This is the main part of the page and contains the HTML tags for the web content.
