4.2 Features Not Supported in HTML 3.2
4.2.1 ISINDEX Element
The Nokia 9210 Communicator’s web browser does not support the ISINDEX element, which is used to create very
simple search pages. This feature is very rarely used, and HTML forms should be used instead. HTML forms offer a
better usability and possibilities to tailor the query page to your needs.
4.2.2 BACKGROUND Attribute of the BODY Element
Background images are not supported. Background images, especially when shown on a small screen, easily distract
the user and make the page harder to read. Background colours are supported.
5. Guidelines for Design
5.1 Validate Your HTML
There are several HTML validators available that validate your documents against HTML Document Type Definition. It
is recommended that authors validate their web pages, because valid HTML is always less prone for incompatibilities
and errors than pages which contain erroneous HTML. This holds true for any browser.
At the time of this writing, the World Wide Web Consortium operates a HTML validator at http://validator.w3.org/.
5.2 Web Site Organization
5.2.1 Avoid ‘doormat’ pages
The user is accessing your web site over a GSM data call, and pays per second. It is not recommended to start your site
using a ‘doormat’ or an ‘intro’ page, which has no functionality other than perhaps to greet the visitor and to display a
logo. It is better to go to your service directly.
