html sub tag and sup tag_HTML/Xhtml_web page production

Today let’s get to know two html tags that I don’t use very often: sub tags and sup tags.
Definition and usage: The
_{tag can define subscript text. ^{can define superscript text. They are all inline elements and are slightly smaller than the current font by default.}}

Example:

This tag is_sub
This tag is^sup

Draw inferences from one example:

Let’s take a look at how to achieve this effect with mathematical equations?

x₁ y₂³=15
< ;/div>



Other applications:

By chance, I discovered Taobao some time ago The website has made some modifications to the price (I don’t know why, but it has now been restored), which is different from the previous traditional price performance.

>

< style type="text/css">



^{￥< /sup>43.₂₆}



I believe that the applications of sub and sup tags are not limited The same goes for other HTML tags. As long as you understand them and activate our thinking and imagination, you can use them skillfully and show their unique charm.
