This article will explain in detail how to use the superscript sup and sub tag elements in HTML. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Html superscript: floating content

The label defines the superscript text.

The content contained in the tag and its closing tag will be displayed at half the height of the characters in the current text stream, but the font and size of the text in the current text stream will be the same.

Tip: this tag is useful for adding footnotes to documents and for representing index values in equations. If used in conjunction with tags, you can create a good hyperlink footnote.

Html subscript: floating content

The label defines the subscript text.

The content contained in the tag and its closing tag will be displayed at half the height of the characters in the current text stream, but the font and size of the text in the current text stream will be the same.

Tip: both the label and the corresponding label are very useful in mathematical equations, scientific symbols, and chemical formulas.

Usage case code

The upper surface of html needs to be tagged with htmlsup, and the content marked under the float should be tagged with htmlsub.

1) the content that needs to be surfaced and tagged before and after tagging

2) subscript content needs to be tagged before and after

3) there are many html tags that often use superscripts or subscripts in chemical expressions. We can use html superscript and subscript tags to solve the problem without using css style.
