What are HTML semantic tags? A complete list of common HTML semantic tags

<strong>1. What are HTML semantic tags?

Semantic tags are designed to give tags their own meaning.

<p>一行文字</p><span>一行文字</span>

As shown in the above code, one of the differences between the <code>p tag and the <code>span tag is that the meaning of the <code>p tag is: paragraph. The <code>span tag has no unique meaning.
