Input types

The <input> attribute that specifies what kind of data field is created. Different values produce text boxes, password fields, number steppers, checkboxes, and more.

Part of: HTML and CSS Journey — Module 28

What it does: type="email" tells the browser to validate the format as an email address. Changing the type value changes the entire field behaviour. type="number" adds a numeric stepper to the field and rejects non-numeric input on submission. type="password" hides the characters for security. 'secret' is not a valid input type. type="checkbox" renders a tick-box. When checked and submitted, the name/value pair is included in the form data. The correct type for phone number inputs is tel, not telephone. Using an invalid type causes the browser to fall back to type="text".

Common mistakes: The type value must be lowercase. 'Email' should be written as 'email': type="email". The type attribute value is missing its closing double quote. It should be type="number" min="1" max="10".
