I have seen in many websites that the text which is flowing stops as soon as we hover our mouse over it , like in this site ,http://www.sofworld.org, how is it done ?
See the source code of that page ,
<marquee
onmouseout="this.setAttribute('scrollamount', 6, 0);"
onmouseover="this.setAttribute('scrollamount', 0, 0);"
scrolldelay="150" scrollamount="6">
Text
</marquee>
