We all know the difference rendering on different browsers and various support for styles and other things on different browsers.
While start developing a site, which browser would be optimal to start and then to proceed with convincing other browsers by various methods.
For e.g. Is it ok to start with IE and then do the necessary changes to display the same in FF and chrome etc? Else start with modern/webkit browsers and then degrade the code according to IE and other low versions.
Also, I would like to know which browsers we can avoid. Many sites have stopped support to IE6. So, as developers we can also start avoiding some sites? If yes, what are all? (which versions of what broswers)
