The <ins> tag is used to note where content has been added to a document.
This tag is for controlling the changes in the versioning of a document. It gives semantic and visual styling with an underline of the change that was made.
In the code below, we made a mistake for Mary. She didn’t have a lamb, but a little lamb. So if we want to keep all version information in the document for historical purposes, we use the <ins> tag to surround the content that is to be added.
The <ins> tag can take two optional attributes:
cite – a http reference to a document URI that describes the change
datetime – a timestamp of when we made the change (YYYY-MM-DDTHH:MM:SS format)
