Insert and Delete

The delete tag (<del>) defines text that has been deleted from a document, and the insert tag (<ins>)defines a text that has been inserted,

Use <del> and <ins> to markup updates and modifications in a document. Browsers will normally strike a line through deleted text and underline inserted text.

<p>If elements are <del>deleted</del> <ins>inserted</ins>, they will have a line through or under them, respectively.</p>
