What Is an "input" Tag/Element?

An "input" element is an inline element that can used inside a "form" element to define an input field. Here are basic rules about an "input" elements:

• An "input" element is an inline element. It can not be used directly inside a "form" element. It can only be used inside a block sub-element of a "form" element.
• An "input" element is an empty content element.
• An "input" element defines an input field which may or may not be visible in a browser.
• An "input" element has an attribute called "type" that allows you to define the type of input field, like a text input, a checkbox, or a radio button.

Here is a tutorial example of a form with 3 input fields:

<?xml version="1.0" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
 <head>
  <title>Input Fields</title>
 </head>
 <body>
  <h4>Online Survey</h4>
  <form action="/survey.php">
  <p style="background-color: #eeeeee; padding: 8px;">
   Your name: <input/><br/>
   You like FYIcenter.com: <input type="checkbox"/><br/>
