	// This is a basic color fade in effect. There are 6 elements in the HTML 
	// section at the end of this document. Each one is a div that contains 
	// a text node. When the page is loaded, the colorfade animation procedure is called. 
	//
	// It moves the text whose id is "text"+el to the right and at the same
	// time changes the color from white (255,255,255) to gray.
	// When both the background and the text are white (255,255,255), 
	// it creates a transparency effect.

						// It's using the acceleration approach. In the beginning 
						// the position is updated by high values (20,19,18..)
						// and in the end it's updated by low values (4,3,2..).
