Strikethrough (extension)
GFM enables the strikethrough extension, where an additional emphasis type is
available.
Strikethrough text is any text wrapped in a matching pair of one or two tildes (~).
~~Hi~~ Hello, ~there~ world!
<p><del>Hi</del> Hello, <del>there</del> world!</p>
As with regular emphasis delimiters, a new paragraph will cause strikethrough parsing to cease:
This ~~has a
new paragraph~~.
<p>This ~~has a</p>
<p>new paragraph~~.</p>
Three or more tildes do not create a strikethrough:
This will ~~~not~~~ strike.
<p>This will ~~~not~~~ strike.</p>
