The moving sign uses the <marquee> command, Margarita. If you find an HTML trick you want to imitate, right-click on the page you like and choose "view source." Then steal whatever you like from the information that appears on your screen. You can cut-and-pase the major stuff, and insert your own changes. Instead of the number codes for colors, you can use the words posted in the chart Bill linked to. The code for my banner message is below.
