A popular browser should be considered any browser that fully complies with HTTP/1.1. Sadly, that's not the real definition. Most people don't think about some of us lynx users when designing webpages. If you really want to build a decent webpage, make it fit to the w3c standards. http://www.w3.org/ http://validator.w3.org/ If it complies fully with the validator, then it should be compatible with all browsers. If theres a browser that isn't compatible with it after the validator, then get another browser
