Strikethrough text without CSS, using native HTML5

[wkan17012021]

Is your feature request related to a problem? Please describe.
Perhaps less well known, is that you can strikethrough text using HTML rather than resorting to CSS, which before researching about this, I would use CSS text-decoration property. A use case could be for displaying old product/service prices with strikethrough, next to the new discounted price. I would like to add this feature as a part of the HTML tips and tricks.

Describe the solution you'd like
Put a demo for the <s> tag in the repo. Note the <strike> tag is deprecated.

Please can you assign this to me?
