increased by configuring it with an accesskeyattribute. Visually challenged
visitors using a screen reader will hear that a submit button has been encoun-
tered. Submit buttons automatically invoke the server-side processing config-
ured in the form tag.
An image button will also automatically invoke the server-side processing
configured for the form and can be more accessible if configured with the alt
and accesskeyattributes. Unless there is a very good reason or a very insis-
tent client, avoid the tag—why make a simple submit button so
complex? If needed, configure the elements contained within the button area
with attributes to improve accessibility such as altand accesskeywhere
appropriate.

1. CGI (Common Gateway Interface) is a standard method for Web pages to request
   special processing on the Web server, such as querying databases, sending e-mails,
   or handling form data. CGI provides a standard way for a Web server to pass
   a Web visitor request to a program or script stored on the server, receive a
   response from the program or script, and send that response to the Web browser
   for display.

   <form method="post"
   action="http://webdevfoundations.net/scripts/subscribe.asp" >
   First Name:

3. The server-side script developer and the Web page designer must work together to
   get both parts of the form processing—the front-end Web page and the back-end
   server-side script—working together. They need to communicate regarding the
   method (get or post) to be used by the form, and the location of the server-side
   script. Since the names of the form elements are often used by the server-side
   script as variable names, the form element names are usually specified at this
   time.
