Using nested <sub> in HTML

We can use nested subscripts in HTML that is a subscript within a subscript. The inner subscript appears as a subscript to the previous subscript.

You can nest any number of subscripts in HTML.

Example of using nested <sub> in HTML:

A<sub>subscript1<sub>subscript2</sub></sub>

Output:

A_{subscript1subscript2}

The alternative of subscript is to put text at the top and it is done using superscript tag <sup> and </sup>. You can learn more about superscript in this article.
