• Browsers can render inserted ( <ins> ) or deleted ( <del> ) text in a different style to
show the changes that have been made to the document. Typically, newly inserted
entries are underlined and deletions appear with strikethrough. In theory, a browser
could have a way to show a revision history on a document, but generally this is left
up to scripting or the environment the page is built in.
<isindex> (Index Prompt)
This element indicates that a document has an associated searchable keyword index. When
a browser encounters this element, it inserts a query entry field at that point in the
document. The viewer can enter query terms to perform a search. This element is
deprecated under the strict HTML and XHTML specifications and should not be used.
