How to Stop Marquee on Mouse Hover???

<marquee>
text to scroll here
<marquee>

and it moves from right to left and loops, than how to stop it on mouseover and then start back up when mouse away from it???

Some simple javascript events are required (which requires that the client’s browser is javascript enabled):

<marquee onmouseover="this.setAttribute('scrollamount', 0, 0);" onmouseout="this.setAttribute('scrollamount', 6, 0);">
text to scroll here
<marquee>

The marquee tag was originally IE specific. It is now supported in limited fashion in some other browsers. FireFox will behave the same as IE for the above example. Opera will reset the marquee to the beginning. Many browsers will do nothing at all, some will not even scroll the marquee to begin with.

If you want more consistent cross browser support and control over a marquee type effect, use a purely javascript marquee.
