Here's another of those utility type pages that I do from time to time. This one grew out of a thought I had about a better way to deliver webpages when a browser may not recognise a style property. Detecting the browser by reading its User Agent string doesn't actually help determine if it will support a particular property, and the best way is to interogate the browser and find if it will react to a prompt using that property. So what follows is a relatively short list of CSS2 styles that were not commonly supported until recently, and a longer list of those styles being developed for the CSS3 specification. As browser designers work on their interpretations and methods of achieving the desired effect, they prefix the nominal W3C style with their own in-house developer prefix, e.g. -ms- (Microsoft IE), -moz- (Mozilla/Gecko Firefox), -o- (Opera), -webkit- (Chrome and Safari), and -khtml- (Konqueror Linux O/S). Usually it is only once they feel confident about their design that they remove the prefix and use the W3C property e.g. -moz-border-radius will become border-radius, however sometimes they leave both properties running side by side. This webpage will show you which of the newer style properties your browser will support. If a developer prefix is shown on any style, it doesn't follow that it will not answer to the standard property, so in that respect it is best to apply all the prefixed styles followed by the standard style, and the browser will respond to the last one it recognises. To the right of the listings that your browser will provide, is a small note which uses the 'transform' style, and those browsers that don't recognise the style will not see the note. Rendition of this animated note is variable between the browsers and is best in Chrome 8 followed by Opera 10.64, Firefox 4.07 and lastly Safari 5. http://freepages.rootsweb.com/~bristowe/test/css-properties/ If you want to check what another browser is capable of, copy and paste the url to http://browsershots.com and make sure you select javascript 'enabled". The greatest CSS3 support is by Chrome 8 and least by IE browsers. Barry
