The <input> Tag

Use the <input> tag to define any one of a number of common form “controls,” as they are called in the HTML 4 and XHTML standards, including text fields, multiple-choice lists, clickable images, and submission buttons. Although there are many attributes for the <input> tag, only the type and name attributes are required for each element (only type for a submission or reset button; see the following explanation). And as we describe in detail later, each type of input control uses only a subset of the allowed attributes. Additional <input> attributes may be required based upon which type of form element you specify.

Table 9-1 summarizes the various form <input> types and attributes, required and optional.
