Technique H89:Using the title attribute to provide context-sensitive help
Applicability
HTML and XHTML
This technique relates to 3.3.5: Help (Advisory).
Description
The objective of this technique is to provide context sensitive help for users as
they enter data in forms by providing the help information in a title
attribute. The help may include format information or examples of input.
Current user agents and assistive technologies do not always provide the information
contained in the title
attribute to users. Avoid using this technique in isolation until the title
attribute has wide-spread support.
Examples
Example 1
A mapping application provides a form consisting of a label "Address:", an input box
and a submit button with value "Find map". The input box has a title
attribute value with an example of the address format the user should enter.
<label for="searchAddress">Address: </label> <input id="searchAddress" type="text" size="30" value="" name="searchAddress" title="Address example: 101 Collins St, Melbourne, Australia" />
Example 2
A form that allows users to pay their bill online requires the user to enter their
account number. The input box associated with the "Account number" label has a title
attribute providing information on locating the account number.
<label for="accNum1">Account number: </label> <input id="accNum1" type="text" size="10" value="" title="Your account number can be found in the top right-hand corner of your bill." />
