+Enter some data and click the *Submit* button. The request gives you an innocent
+stare and displays “No server” because you are not running the server on your
+machine.
+
+This example show how to use a form to collect data from a user.
+
+A form usually contains several input elements for entering data of various
+kinds, such as names and addresses, birthdays, email addresses, and so on.
+HTML supports several kinds of input elements, including text fields, text
+areas, radio buttons, and checkboxes. HTML5 adds more specialized input
+elements such as email and password fields, color pickers, date and time
+widgets, and range elements.
+
+A form has an action, which is a URL to which to send the form data, and a
+method, which indicates how the form data is to be sent. The action and the
+method can be specified declaratively within HTML, or you can write Dart code
+and use Dart libraries to perform the action programmatically.
