HTML s tag is an HTML tag that allows us to write strikethrough text.
However, its usage has been changed with HTML5. It is now used to define incorrect or irrelevant texts. This tag is sometimes confused with del, but there is a difference between them in terms of their usage.
As indicated above, s is used to define incorrect or irrelevant texts whereas del is used to define deleted text.
