<h3>RGB Slider</h3>
<p>
The RGB slider implements three slider controls to generate a
RGB color. The background color of each slider is also
dynamically modified to reflect the colors that could be
generated by moving a single slider.

<h3>Basic Sliders</h3>
<p>
The slider widget is an implementation of YAHOO.util.DragDrop
It also will use YAHOO.util.Animation if available to
animate the movement of the thumb when you click the
slider background.
The only difference between the two sliders aside from
the fact that one is vertical and one horizontal is that
the horizontal slider implements the "tick mark" feature
of drag and drop; it will "snap" to the tick marks spaced
25 pixels apart.

<h3>Sliders</h3>
<p>
The slider widget is an implementation of YAHOO.util.DragDrop
It also will use YAHOO.util.Animation if available to
animate the movement of the thumb when you click the
slider background.
The only difference between the two sliders aside from
the fact that one is vertical and one horizontal is that
the horizontal slider implements the "tick mark" feature
of drag and drop; it will "snap" to the tick marks spaced
25 pixels apart.
