This JavaScript code do not use MARQUEE tag but features & actions are similar to this tag, meaning you can make some page content that continuously move by the four directions, stop moving on mouseover,... With this code, almost you only use JavaScript to install a "MARQUEE" for dynamic content. The web contents are simply defined as normal HTML, contained in a DIV element with a unique ID attribute.

Label: crawling, content, page content, web content, dynamic content, MARQUEE, directions, stop moving, mouseover
