HTML <strike> Tag
Not Supported in HTML5.
<strike> tag was used in HTML 4 to define strikethrough text.
What to Use Instead?
Use the <del> tag to define deleted text:
<p>My favorite color is <del > blue</del> <ins > red</ins>!</p >
Use the <s> tag to mark up text that is no longer correct:
<p><s > My car is blue.</s></p >
