Inline Elements - Revision Marks
HTML 4.0 introduces two new phrase elements for specifying revisions to your document. The <INS> and <DEL>
elements can be useful for tracking changes to a page. Both of these elements have a default rendering to help visually distinguish insertions
and deletions. As with all phrase elements, this rendering is merely a browser default and can be customized using a style sheet.
Currently IE4 is the only browser that supports INS and DEL. These elements
have no effect on other browsers
Both <INS> and <DEL> have two attributes that help track the changes:
cite = uri
- The value of this attribute is a URI that designates a source document or message. This attribute is intended to point to information explaining why a document was changed.
datetime = datetime
- The value of this attribute specifies the date and time when the change was made.
Currently Internet Explorer 4.0 does not do anything with these attributes, but they are accessible from script.
For example, in this paragraph clicking on the following Inserted Text displays the date and time the contents were
inserted. The syntax for defining a datetime is specified by ISO8601 and in the HTML 4.0 specification.
