A simple way to provide a Web site visitor with information is to add a scrolling text
message to a Web page. Companies often use scrolling messages on their Web sites to
highlight breaking news, key products, or special promotions. A scrolling text message
can appear either in a text field within the Web page or on the status bar in the browser
window. Because visitors to a Web page often do not look at the status bar, placing the
scrolling message in a prominent place on the Web page is a better location.
A scrolling message has four basic components:
The display object (a form text field)•
The text message to scroll in the text field•
The position of the next character in the text message
A time delay
The display object identifies where the scrolling message is displayed, which, in
this project, is in a form text field. The scrolling message is a text string assigned to a
variable. The text string is what the user sees when the message is displayed. The position
is the location of the next character in the text string. The delay regulates the speed in
which the characters display in the text field.
The first step in creating the scrolling message for the Shoreline State Bank Web

object to display a scrolling message is a text field. The text field must be part of a form
object. In the Shoreline State Bank Web page, you will place the form and text field below
You must name the form using the id attribute and the text field using the name
attribute. The <form> id serves as the object and the <input> name serves as a property
attribute of the text field indicates the display width of the text field.
