DEBUGGING SKILLS (10 Points)
If your home computer does not have internet access, you may want to do this in class
before you leave, or come back another time this week.
Download and unzip the file csis1-spring08-test2.zip under the “skills portion” link from the
class website (posted after class). Open the folder and click on homepage.html. The web
page that comes up has a few bugs. Fix it so a) the page looks like the image below, b) the
disclaimer link pulls up the disclaimer.html file (which is in the same folder) and c) all html
errors are fixed, even if those errors do not produce visible problems in Internet Explorer 7.
When it works, print out your corrected HTML code, the Browser view of the page, and
staple them to this page.
