Synopsis

The input element is used to create a variety of form input controls. The type of control is defined by the type attribute. Following is a complete list of attributes (with descriptions) that can be used with the input element. Not all attributes can be used with all control types. The attributes associated with each control type are listed below.

HTML5 adds a number of new values for the type attribute: datetime, datetime-local, date, month, week, time, number, range, email, url, search, and color. New HTML5 attributes for the input element are listed below.
