Looking for a way to allow your website visitors to communicate with you? This chapter shows you how to build forms that gather information from users and send it to web servers for processing. You can build forms that allow users to send feedback about a site or buy products by submitting credit card information. To create a form, you can use a variety of input fields, including text fields, check boxes, drop-down menus, and radio buttons. The sections in this chapter describe how to add these fields and when to use them.
