the JavaScript has been added. This problem requires using JavaScript to change the scroll bar color,
to display a dynamic message, and display copyright information and the date the Web page was last
modified. The problem also requires adding event handlers in the <body> tag to invoke the JavaScript
user-defined functions.
Perform the following tasks:
1. Using Figure 9-3 on page HTML 416 as a guide, enter a <div> tag with an id name of countDown
between the two orange divider images (hrimg-summercamp.jpg) at line 50.
2. Enter the beginning of a JavaScript code section for a user-defined function in the <head> section
of the Web page before the <style> tag. Be sure to include a comment line to hide the JavaScript
from old browsers.
3. Using the code in Tables 9-15, 9-17, and 9-19 on pages HTML 422, 425, and 427 as a guide, write
a JavaScript user-defined function to display the countdown message shown in Figure 9-19. Use
your own current and future dates for this Web page.
