Basic tags for web pages
1. Title tag
Basic heading tags: The first-level headings are the largest, and successively smaller and smaller.
<h1>First-level tags</h1>
<h2>Second-level tags</h2>
<h3>Third-level tags</h3>
<h4>Four-level tags</h4>
<h5>Five-level tags</h5>
<h6>Six-level label</h6>
The code example is as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>标题标签学习</title>
</head>
<body>
<h1>一级标签</h1>
<h2>二级标签</h2>
<h3>三级标签</h3>
<h4>四级标签</h4>
<h5>五级标签</h5>
<h6>六级标签</h6>

3. Newline label
<br/>
<br>The tag is an empty tag, that is, there is no closing tag, so <br>…</br> is wrong. It must be written in xml.<br/>Because xml requires all tags to be closed, add / Indicates that the label is closed. The two have the same effect, but the former is the old html specification, and in the new specification W3C//DTD HTML 4.0 requires that everything should have a terminator like xml in order to strictly regulate.
The code example is as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>换行标签学习</title>
</head>
<body>
<!-- 未使用换行标签 !-->

The difference between paragraph tags and line break tags: In the generated web page, there is a space before and after the paragraph, but there is no space between each line of the line break.
4. Horizontal line label
<hr/>
In HTML, the <hr> tag does not have an end tag. In XHTML, the <hr> must be closed correctly, such as <hr/>, the same as the <br/> tag. It is used by the standard and needs to be followed by a backslash Kong.
The code example is as follows:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>水平线标签学习</title>
</head>
<body>
hello
<hr/>
world
