In this column we discovered some major differences between Navigator 4.0x and Internet Explorer 4.0x. Navigator treats a positioned element as an independant document, while Explorer exposes various properties that let you handle the element. We also explained the basics of browser detection and object detection, which are explained in detail in Column 6, Browser Compatibility.
