Hi Kiki,
Restrict formatting of a document
------------------------------------------------------------------
When you restrict the formatting of a document, you prevent users from
applying styles that you don't explicitly make available. You also prevent
users from applying formatting directly to text, such as bulleted or
numbered lists or font characteristics. When formatting is restricted, the
commands and keyboard shortcuts for applying formatting directly are
unavailable.
On the Tools menu, click Protect Document.
In the Protect Document task pane, select the Limit formatting to a
selection of styles check box.
Click Settings.
In the list of formatting styles in the Formatting Restrictions dialog box,
select the check boxes for the styles you want to allow, and clear the
check boxes for the styles you don't want to allow in the document.
Tips
To limit formatting to the minimum number of recommended choices, click
Recommended Minimum. You can restrict formatting to fewer choices, but
doing so removes styles that Microsoft Word uses in certain features, such
as tables of contents and bulleted or numbered lists.
If you want to retain certain AutoFormat features, such as changing "1/2"
to "½," select the Allow AutoFormat to override formatting restrictions
check box.
Click Yes, Start Enforcing Protection.
Type a password in the Enter new password (optional) box, and then confirm
the password.
You would have many options for protecting document in Word.
Please let me know has this helped You...
Thank you...
Raghu..
