Attributes are often in use are:

BGCOLOR = "color" -> To set the background color (background) text

DIRECTION = "left / right / up / down" -> Set the text direction of movement

BEHAVIOR = "scroll / slide / alternate" -> To set the behavior of the moving

Scroll -> moving text rotates
Slide -> move the text once and then stopped
Alternate -> text moves from left to right and then back again (back and forth bo)

TITLE = "message" -> message will appear when the mouse is above the text

SCROLLMOUNT = "number" -> set the speed of movement in pixels, the greater the number semajin fast movements.

SCROLLDELAY = "number" -> To set the delay time in milli seconds

LOOP = "number | -1 | infinite" -> Set the number of loops

WIDTH = "width" -> Set the width of the text block in pixels or percent

To be more clear I will include for example:

Marquee example of the movement:

<MARQUEE align="center" direction="left" height="200" scrollamount="2" width="30%">
marquee from right to left
</MARQUEE>

results:
