The <del> Tag in HTML 5

The <del> tag for deletions is one of the editing tags for tracking changes in HTML 5. It is used to mark up text and/or HTML code to indicate that it has in effect been removed instead of actually deleting it from the document. This approach to editing changes in HTML documents can be used to provide a standing record of the original text of articles, blog entries or other edited documents. When the deletions are to be displayed, a different style, often text-decoration: line-through to select a strike-through font, can be used to provide a visual indication of the deleted content or the deletions can be hidden from view with the display: none style.

Likewise, the <ins> editing tag can be used to mark up new text and/or HTML code inserted into a document.

The difference between the <s> (strike) and <del> tags is that <del> is, in effect, as good as deleting the content from the document, while striking content using the <s> tag is for content that is to be included in the document and just visually appear as stricken.
