A non-standard HTML element that causes text to scroll automatically
The marquee
element is a non-standard HTML element. It causes text to move up, down, left or right in a web browser.
It was introduced in early versions of Internet Explorer to enhance the appearance of web pages. It is still supported by Internet Explorer and is now also supported by Firefox, Opera, Chrome and Safari for legacy reasons.
It is not part of any HTML standard and web pages that contain it are not standards compliant.
