I used markup:

<div id="scroll">
<marquee behavior="scroll" direction="left" scrollamount="50">
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
<p>Here is some scrolling text... right to left!</p>
</marquee>
</div>
