How to use title tags and paragraph tags in XHTML

This time I will show you how to use title tags and paragraph tags in XHTML, and what are the precautions for using title tags and paragraph tags in XHTML. The following is a practical case. Get up and take a look.

XHTML Title Overview

When we write Word documents, we often use titles, such as "Chapter 1", "1.2.1", etc. There is also the concept of title in XHTML syntax. Six levels of titles are defined in XHTML, namely 4a249f0d628e2318394fd9b75b4636b1 to 4e9ee319e0fa4abc21ff286eeb145ecc:

<h1>第一级标题</h1>  
<h2>第二级标题</h2>  
<h3>第三级标题</h3>  
<h4>第四级标题</h4>  
<h5>第五级标题</h5>  
<h6>第六级标题</h6>

Use of titles

In XHTML documents, titles are very important, search
IndexEngine uses titles to index the structure and content of your web pages. We must be good at using titles to identify our document hierarchy. Among the titles, the first level title is the highest, and then decreases in sequence. Generally speaking, in XHTML documents, the title applies to the following places in the document (within the 6c04bd5ca3fcae76e30b72ad730ca86d tag):
According to the website level:

<h1>定义网站标题
<h2>定义网站导航或者栏目
<h3>定义文章标题

According to the website content:

<h1>定义网站标题
<h2>定义文章标题
<h3>定义栏目标题

For h4 to h6 titles larger than h3, you can choose them in appropriate places, such as copyright statements or disclaimer notices and other relatively important places.

Also please note that the levels must be decreasing. The level below h1 should be h2, and then h3...

Some suggestions for using titles
Since h1 names the core content of the entire page, generally h1 can only appear once (this is not absolutely the case, but it must not appear multiple times) and used in the most emphasized part of the article. Therefore, if for a specific content page, h1 is often used in the title of the article to highlight the importance of the article, such as this site:

<h1>XHTML 标题<h1>

At this time, whether the website title (website logo) uses h1 again will depend on the actual situation. It depends.

Paragraph p tag

In XHTML, a paragraph is defined through the e388a4556c0f65e1904146cc1a846bee94b3e26ee717c64999d7867364b1b4a3 tag.
XHTML paragraph
Paragraph tag example:

<p>这是一个段落。</p>

In actual production work, we use a large number of e388a4556c0f65e1904146cc1a846bee94b3e26ee717c64999d7867364b1b4a3 paragraph tags.

After adding a paragraph tag to the text, the browser will automatically add a paragraph break to the text. But instead of relying on the empty e388a4556c0f65e1904146cc1a846bee94b3e26ee717c64999d7867364b1b4a3 to form a blank line, we should use the df250b2156c434f3390392d09b1c9563 line break tag.

Line breakdf250b2156c434f3390392d09b1c9563

In XHTML documents, the title or paragraph tag only provides a line break tag. If we need a blank line or multiple line breaks, we need a line break tag3758937f2e19267c4b26eb8fbb84b4a2 . In XHTML, hitting the Enter key to break a new line when editing Word is invalid, and the browser will ignore the new line gap generated in this way.
Example:

<p>这是一些内容</p>  
<br /><br />  
<p>这是另一些内容</p>

Since the line break tag only informs the browser that this place needs a line break, but has no substantive content, this tag does not appear in pairs, and a df250b2156c434f3390392d09b1c9563 only breaks the line. Once, multiple line breaks are required, please enter multiple df250b2156c434f3390392d09b1c9563 tags.

If the df250b2156c434f3390392d09b1c9563 tag is inserted in e388a4556c0f65e1904146cc1a846bee94b3e26ee717c64999d7867364b1b4a3, it will also produce a line break effect.

df250b2156c434f3390392d09b1c9563 or 0c6dc11e160d3b678d68754cc175188a?
Although we can still achieve line breaks using 0c6dc11e160d3b678d68754cc175188a, that is the result of the browser being compatible with the HTML4.0 specification.
In the XHTML specification, for tags that are not paired, you only need to add a space after the end of the content, and then use /> to close the tag, such as df250b2156c434f3390392d09b1c9563 and 5338256240b65edb45cb3136257dd5d273a3ca28445b1c625f2086a50cb8c7df and other tags.
So it's df250b2156c434f3390392d09b1c9563 instead of 076402276aae5dbec7f672f8f4e5cc81 or 0c6dc11e160d3b678d68754cc175188a .
