Difference between id and name attributes in HTML?

Question

What is the difference between the `id` and `name` attributes? They both seem to serve the same purpose of providing an identifier.I would like to know (specifically with regards to HTML forms) whether or not using both is necessary or encouraged for any reasons.

Answer 1

The ID of an HTML tag has no relationship to the data contained within the element. IDs are used to reference the HTML element by JavaScript and CSS.

The name attribute is used when sending data in a form submission when an HTTP request is sent by your browser to the server.
