HTML 5 <input> tag

Definition and Usage

The <input> tag defines the start of an input field where the user can enter data.

Differences Between HTML 4.01 and HTML 5

HTML 5 has many new attributes, and some HTML 4.01 attributes are no longer supported.

In HTML 5 the type attribute has a lot of new values.

Tips and Notes

Note: The input element is empty, it contains attributes only.

Tip: Use the label element to define a label to a form control.
