The <marquee> tag is used to create a scrolling text or image in HTML. It was first introduced in Internet Explorer and was later adopted by other web browsers.
However, it is considered a non-standard element and its use is not recommended because it can create accessibility issues and is not supported by all web browsers.
It is better to use alternative methods to create scrolling content, such as using CSS or JavaScript.
The <marquee> tag is a non-standard HTML element that is used to scroll a text or image either horizontally or vertically.
In simple words, we can say that it automatically scrolls the image or text in up, down, left, and right direction.
