HTML sub tag and sup tag

Today I will introduce two HTML tags that I don’t use very often: the sub tag and the sup tag.
Definition and Usage:
The <sub> tag defines subscript text. <sup> defines superscript text. They are all inline elements and are slightly smaller than the current font by default.

example:

Let’s see how to achieve this effect with mathematical equations.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>sub and sup tags in html</title>>
</head>
<style type="text/css">

</style>
<body>
<span class="price"><sup>￥</sup>43.<sub>26</sub></span>
</body>
</html>
