The banner is now displayed below the drop-down list. Switch to the other theme and you’ll see
the same banner appear. When you click the banner, a new window is opened that takes you to the
site you linked to in the previous exercise. If you don’t see the banner appear at all, check to see if you’re running ad-blocking software on Windows or in your browser. For example, Firefox has an add-on called Adblock Plus that may block the banner in your web page based on its dimensions.
