Click the text “Enter.” This link is to an HTML page called frameset.html.
Although you can see content in this page, frameset.html only contains code for the site's frame set. The content pages are separate HTML pages that open up inside the frame set.
Notice that the page has three frames: the information about the grasshopper's head is the main frame, the list of contents is another frame, and the animated image at the bottom of the page is another.
