In the case of a
Web browser, both the UI and the application functions are
generated on the basis of the code of the Web page itself. This
How can the user
make sure that the
page he is looking
for is the one he
intended to visit?
A familiar environment
offers certain
???landmarks??? that
the user can leverage
for understanding
what is
going on
The Babel of Web User Interfaces 81
means that the rendered UI can be wired to literally any logic;
it??™s like a world where the application creates its own laws of
physics. If the authentication functions are part of that world,
with no in?¬‚uence from elements living outside the rendering
area of the browser, there??™s no way for the user to know what
will really happen to the data he will type in.
As stressed at the beginning of the section, credential gathering
on the Internet is something that has to be dealt with at the application
level. If it has to be a feature of your application, of
course you want to be free to adapt the look and feel of the credential-
gathering controls to the overall style of your application!
So if all your controls have a border 7 pixels wide and
left-justi?¬?ed, your username and password ?¬?elds will follow suit.
