What is pupose of "SUB" tag in HTML?

Hi:

What is actually purpose of "SUB" tag in HTML?

Is it some kind of Subtract operator? or something else?

 

sub stands for substring

 

actually it stands for sub-script.

that is it sets the text below the regular position for text. (SUP puts it above)

 

SUB stands for Subscript.
Sub tag is generally used for mathematical equations like a(square)+b(square)+2ab.

Thanks.

 

BWAHAHA... Thanks I needed a laugh... I've not laughed at HTML misunderstanding that much since someone was claiming DIV stood for 'divvy and DL stood for "data list".

Listen to everyone else on this thread, they got it right.

There are LOT of elements people forget or don't use, but that goes for HTML in general... ACRONYM, ABBR, CAPTION, LEGEND, LABEL, TH, DFN, KBD, VAR...

I swear I see one more IDIOT doing this:

I'm gonna puke.
