The <ins> Tag in HTML 5
The <ins> tag for insertions is one of the editing tags for tracking changes in HTML 5. It is used to mark up new text and/or HTML code inserted into a 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. A different text color (sometimes color: green) or other style can be used to provide a visual indication of the insertions.
Likewise, the <del> editing tag can be 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.
