Using HTML tags is supposed to work with GitHub Markdown but, in particular, <s>text</s> is not working for me. It used to work on the now deprecated live preview page, but not on preview of README.md file. It works on wikis. I didn't find any special syntax for strikethrough on the Markdown: Syntax page.

Is it not possible?


Use ~~double tildes around the words~~.

I just used the following syntax

<del> ... </del>

successfully on GitHub in an issue description.

    This is a good answer too, since Markdown accepts arbitrary HTML tags. Depends on how you want to use it. – Ian Greenleaf Young Apr 26 '13 at 23:34

I know this is an old question, but I don't see a very detailed answer of the possibilities to strikethrough your text. So here's my answer:

There are several ways to do it:

  1. <strike>strike</strike>strike
  2. <del>strike</del>strike
  3. <s>strike</s>strike
  4. ~~strike~~ → ~~strike~~
  5. ~strike~ → ~strike~

Because tildes don't work on Stack Exchange (later: SE) platforms, the HTML syntax is the most correct way to strike your text. This syntax is a little "hack" to do the same thing instead of the markdown notations.

Because there is no universal notation for markdown text, the notations may be different for each platform. Here is an overview for several platforms:

The GitHub Flavored Markdown only mentions that you can use double tilde, but you can use everything.

    Great answer, it's more comprehensive than the accepted, as it provides alternatives to places where ~~ doesn't work ~~ In Multimarkdown and Marked2, the tilde doesn't work for me. – Paul Solt Aug 8 '18 at 15:35
  • To bad <s>the html</s> doesn't work in comments. – Chloe Jan 31 '19 at 4:23
  • I just confirmed that on Keybase chat, ~~ around characters does strike them out. – Derek Mahar Oct 19 '19 at 13:22

    Slack takes one tilde only: ~like so~ in messages – scrat.squirrel Mar 3 at 23:05

Just use ~ to enclose whatever you want to strike.

Here's a GIF.

Just use ~ character at the start and the end in markdown.

<s> and </s> is the only thing working
~ and ~~ both of them are not working under
