>2) Colors, How do get the "#0000f00" numbers for setting colors, I want to >change the background colors, but don't have the ability to match anything. >Is there a formula, or did I have to go to MIT? ;) Well, you have to understand the hexadecimal number system and basic color principles. Each color specifier is three two-digit hexadecimal numbers. They represent, in order, the intensity of red, green, and blue light in the color. FF is full intensity, and 00 is none. For example, #000000 is black, #FFFFFF is white, and #FF0000 is pure red. #808080 is gray and #808000 is a half-intensity yellow. The ability to pick the primary colors out of a mix comes with practice. BTW, never use #FFFFFF as a text color in a Netscape document. There is a bug in the windows version that will make the text invisible. You should use #FEFEFE instead. Myles Williams
