How a marquee tag is useful to paragraph and image
does not support HTML5 Marquee tag, it is old tag
I think it is unusual element nowadays, nobody uses it
But tell something that how it works
The <marquee> tag creates a creeping line on the page. In fact, the content of the <marquee> container is not limited to lines and allows you to move (scroll) any elements of a web page - images, text, tables, form elements, etc. The movement can be set not only horizontally, but also vertically, in this case the dimensions of the area in which the movement will occur are indicated. Try this: <marquee behavior="alternate" direction="left" bgcolor="#ffcc00"> I'm a marquee tag </marquee>
I think it makes users get nervous.
