Revisions: del and ins
There may be times when you need to update a phrase in your document but would like to clearly indicate
what was updated. This is a job for the
del
and
ins
elements:
del
indicates deleted text, and
ins
indicates inserted text. Both
del
and
ins
may optionally include a
cite
attribute bearing the URL of a
page with details about the change and a
datetime
attribute to mark the date and time the revision was
made. You can also include a short note about the change in a
title
attribute, as Listing 4-37 shows.
Listing 4-37.
Revisions noted with the
del
and
ins
elements
<p>We'll be closed on
<del datetime="2012-04-19">Friday</del>
<ins datetime="2012-04-19" title="minor shipping delay">Saturday</ins>
for installation of a new fluxomolecular extrusion loom.</p>
Most web browsers display the contents of
del
as a strikethrough (a horizontal line drawn through the
text), and display the
ins
element as underlined text, as shown in Figure 4-23. It's conventional for
inserted text to follow the deleted text.
