HTML <sub> (Subscript) Tag

<p>This is <sub>subscript</sub> text</p>

Meaning

The <sub> element renders its content as subscripted text.

The <sub> tag should be used for typographical reasons only.

Notes:

• The CSS property vertical-align can be used to simulate this element.
• This tag must not be used for styling purpose like changing the vertical position of the text. In that case CSS should be used instead: the vertical-align property with the sub value will achieve the same effect.
