Html semantic tags, new semantic tags in Html5

During my study, I compiled some knowledge about semantic tags in HTML, but the list is not comprehensive.

I hope you all have it If you have any new insights, you can leave me a message and I will add them. Thank you all

1. What are semantic tags?

So what is semantic tags? To put it simply, understand each tag. The purpose of each tag (under what circumstances can I use this tag?) For example,

The title of the article on the webpage can use the title tag, and the of each column on the webpage can be used 🎜>Column nameYou can also use title tags.

The content paragraphs in the article must be placed in the paragraph tag . If there is text that you want to emphasize in the article, you can use the em tag to express emphasis, etc.

2. Why use semantic tags?

1. It is easier to be indexed by search engines.

2. Make it easier for screen readers to read web content.

3. Can better reflect the theme of the page

4. Better compatibility, supports more network devices
