safely compatible with all browsers, so you must be careful what properties you use. You do not want to negatively effect your visitors' experience at your site. Obviously, if your visitor is using an older version of Netscape to surf your site, and you have colored scrolls bars which do not display in Netscape, that would be considered a safe, cosmetic property. This is because the visitor using this old browser does not know the scrollbars are displayed in a different color if they were viewing your site with MIE, for example. This does not effect their navigation through your site. If it did, we would not consider it a safe, cosmetic CSS property. In essence, based on what I described above, using external CSS makes maintenance to your site's cosmetic appearance quite easy to maintain site-wide. Recently, we updated the appearance of our entire site, BasicTemplates.com, by changing the font-family and size. If you have been to our site before and have viewed it now, you will find this a refreshing new appearance. Feedback poured in about how much our visitors enjoyed the "new look". A few folks even remarked about how time consuming the change must have been since our site is so large. ]
