These two elements are used to mark document changes regarding inserted or deleted parts of it, and in respect with the rest of the document.

They are often used as a part of a draft document, or a document in progress, subdued to changes.

Both elements can be used as a block level element or an inline level element, but not both. Thus they can be used within a paragraph or contain one, but both situations are not allowed.

The rendering of those two elements depends on the user agent but it should be obvious, i.e. <del> element might have text marked with strikethrough while <ins> element might change the color of text.

Syntax:

<ins></ins>, <del></del>
