HTML <strike> tag
The <strike> tag is used to define strike through a given text to mark it as an incorrect text.
Initially, the <s> was also used to strike through the text but the <s> tag was also deprecated in HTML4 but reconsidered in HTML5. So, it is better to use <del> tag instead of <s> or <strike> tags.
Alternatively, you can also use the CSS property text-decoration: line-through.
