Netscape Extensions
Netscape has a knack for pleasing Web designers. They�ve created even more HTML codes (usually called HTML tags) known as Netscape Extensions.
Unlike this page in this book, which was printed with an exact page layout specification, the Web browser interprets the HTML codes. Sometimes the HTML codes and the browser don�t communicate very well, and the page looks differently than the Web designer expected.
With Netscape extensions, however, Web designers can jump the user hurdle. They protect their Web documents and can specify relative typeface size (such as larger or smaller than another font) and color (such as red or maroon). Web developers can also use Netscape frames to divide the Web browser window into different �panes� or frames. Developers can put a table of contents on one side of the page and display the different chapters of the site on the other side of the page.
The only problem with Netscape extensions is that you can�t count on every browser to support the extensions. Microsoft Internet Explorer only grudgingly (Microsoft calls the codes �Netscapisms�) accepted the codes in their newer browser versions.
