<BASEFONT> tag is used to specify the default setting of the text. It takes the same attributes as <FONT> tag. The only difference is that the <BASEFONT> tag affects all the text that follows until a new tag affect that is encountered. <FONT> tag affects the text that comes upto its closing </FONT> tag.e.g.<HTML><BODY><BASEFONT size=“2” color=“Red'>Hi Everyone<FONT size=“4”>HTML is a Web language </FONT>It is used for creating Web pages.</BODY></HTML>Here, in the above example only the text enclosed in <FONT> </FONT> is affected by font setting, rest of the text gets affected by basefont setting.
