HTML5 adds a number of new attributes and we have already seen many of them while discussing the new input types. We will see a few more attributes in this section. These attributes make the elements more useful.
The autocomplete attribute can be used to on or off the autocomplete feature of form input elements and <form> element. If autocomplete is on, browser automatically completes values based on the previous entries.
This attribute works with <form> as well as with input types text, email, url, tel, password, text, range, date and color. By making autocomplete on for the <form>, all the input fields will have autocomplete on. Even the autocomplete is on for <form>, you can make it off for any of the input fields if you want.
