You should test this page with Netscape and MS IE browsers in order to see the difference, but I try to demoNetscapetrate text style differences.
If you use MS IE 4.01+ look at this text and the preceding header. The top header and paragraph look out like this, when you use a Netscape 4.x browser.
If you use a Netscape 4.x browser, look at the text. The text in the top paragraph is this size, when you use a MS IE browser.
I have tried to show with nested block elements to users of MS IE, how Netscape 4.04 could render the first heading element I give to it all properties, which I have defined to MS IE 4.x+, Opera 3.x+ and Netscape 6.x+ browsers.
Note. The font size is in MS IE 6.0 for Windows DTD-dependent. In this case it means that with a different DTD MS IE 6.0 would render the font size one step smaller than in this model page. MS IE 5.0 for Mac render relative font sizes ovellall differently even if the behavior is not DTD-dependent.
