Example and JavaScript of single marquee

Example:

NTMM is a fun place to learn.

<script language="JavaScript1.2">
<!--
var scroll_delay_ms_m = 100;  // delay of each scroll in milliseconds
var scroll_distance_px_m = 5; // distance of each scroll in pixels
var layer_m1 = document.layers["marquee"];
var lw = layer_m1.clip.width;
var dw = document.width;
var ns = (document.layers) ? 1 : 0;
if (ns) {
  layer_m1.left = dw;
  marquee(); }
function marquee(){
  layer_m1.visibility = "show";
if(layer_m1.left > -lw ) layer_m1.left -= scroll_distance_px_m;
  else layer_m1.left = dw;
timerID = setTimeout(marquee, scroll_delay_ms_m);}
// Single Marquee script for Messenger.
// Dec/20/1999 Ver 3.0 for plugin.
// NTMM-JV: Joji & rene --></script>

Note: Script will be changed if you choose left to right scrolling.
