hi, do you know if is there some script or code to add in css file or in html file to make the css compatible with all version of browser? thank you
Sorry there isn't a magic fix like you are searching for. Browser compatability can only be achieved by using the correct coding methods (coding to standards), and then adding appropriate fixes for inadequate browsers (like IE6), but these will often not be required. So if your site is not browser compatabile, the number 1 cause is poor coding.
