<strike></strike> element has been deprecated since HTML 4 in favor of the CSS
text-decoration:line-through;. It is used to create a strike through text. It is now obsolete in HTML5. If it represents deleted content, use the
<del> instead; in all other cases use the CSS
text-decoration property. This element is synonymous to the
<s> element, which produces the same result.
