/*

 <whew> After 2 days of researching and parsing the codes of others
 i finally was able to make a text fade-in/out script <g>

 Unfortunately, this can only do 3 colors, Red, Green and Blue.
 But don't worry, I'm working on it so that it'll work with any color
 and background. And do excuse the extra codes... this is my
 first script.

 Anyway, feel free to use the script but do pls include this little
 copyright...

 btw, the script works for IE4 and NS4 :)

// Syntax for use:

//     gradient(TEXT_STRING_HERE,HEXCODES_STRING_HERE);

//  use in similar way you would use document.write();
//  note, it cannot be used to return a string value.
//  gradient() takes two arguements. the first will
//  be the original pure text string. (no htmlcodes)
//  the second argument is a string of color hexcodes
//  seperated with spaces thru which the text should
//  progress. for example say you wanted to print out
//  the string "color gradient", and you wanted it to
//  progress from blue to red. a color code for blue
//  is 4444FF, and a color code for red is FF4444.
//  taking those two codes, and the original string,
//  somewhere in the body of the document you would
//  write within a <Script> tag the following:
//  gradient("color gradient","4444FF FF4444");
//  if however, you wanted it to progress thru three
//  or more colors, its as simple as adding them to the
//  string of color codes. it is important to remember
//  however that the string must be color HEXCODES, and
//  not merely just color names, (e.x- "red", "yellow")
//  if this seems like too much trouble, then perhaps
//  you should try something simple like ripping off
//  some annoying status bar text scroller. =Þ
//  one last thing. if you overuse this script, i can
//  pretty much gaurantee people will hate your webpage.
