Viewing problems? & Help?

Today while in lecture I borrowed a friend's computer and his wireless to do some internet housekeeping and realized that this page, when viewed on Internet Explorer, does not look like this as it does on Mozilla--

But rather, looks like this--

So now I'm wondering how many of you guys have this problem, if there are any other problems, and if anyone knows how to code the format so that everything shows up as it does in the top picture? Any advice and feedback would be appreciated! Thanks :)
