To add a moving text (also called marquee) effect use :

    <marquee>Add your text here....</marquee>


This will show as this :

Add your text here....

You can change the direction of the text by using this tag in the beginning :

    <marquee direction="right">

Instead of 'right' put 'up' or 'down' or 'left' as per your...
preference. To add a background color use this code :

<marquee direction="right" width="100%" style="background:#EC4F52"><font color="white">Add your text here...</font></marquee>
