Request user data

input

An input field provides an interface between the browser and the user which allows data to be requested in specific ways.

The input element is multi-faceted, presenting itself to the user as: text input, radio buttons, check boxes, buttons, color pickers, dates and times, and more.

Input elements are typically placed subordinate to a form element.
