Create a hue slider with CSS gradients

Yes, That Is A Fancy Way Of Saying Rainbows

For most browsers, you can use the linear gradient vendor property with multiple color stops. In IE, the filter property does not support color stops, so we have to fake it with 6 divs, each with a single color stop gradient. It works in Internet Explorer, back to version 5.5.

I made this while working on my JavaScript colorpicker, Spectrum. Check out the hue slider gradient demo on jsfiddle, where you can play with the source.

#hue {
    height:200px;
    width: 40px;

    background: -moz-linear-gradient(top, #ff0000 0%, #ffff00 17%, #00ff00 33%, #00ffff 50%, #0000ff 67%, #ff00ff 83%, #ff0000 100%);
    background: -ms-linear-gradient(top, #ff0000 0%, #ffff00 17%, #00ff00 33%, #00ffff 50%, #0000ff 67%, #ff00ff 83%, #ff0000 100%);
    background: -o-linear-gradient(top, #ff0000 0%, #ffff00 17%, #00ff00 33%, #00ffff 50%, #0000ff 67%, #ff00ff 83%, #ff0000 100%);
    background: -webkit-gradient(linear, left top, left bottom, from(#ff0000), color-stop(0.17, #ffff00), color-stop(0.33, #00ff00), color-stop(0.5, #00ffff), color-stop(0.67, #0000ff), color-stop(0.83, #ff00ff), to(#ff0000));
    background: -webkit-linear-gradient(top, #ff0000 0%, #ffff00 17%, #00ff00 33%, #00ffff 50%, #0000ff 67%, #ff00ff 83%, #ff0000 100%);
    background: linear-gradient(to bottom, #ff0000 0%, #ffff00 17%, #00ff00 33%, #00ffff 50%, #0000ff 67%, #ff00ff 83%, #ff0000 100%);
}

#ie-1 {
    height:17%;
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ff0000', endColorstr='#ffff00');
}
#ie-2 {
    height:16%;
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffff00', endColorstr='#00ff00');
}
#ie-3 {
    height:17%;
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#00ff00', endColorstr='#00ffff');
}
#ie-4 {
    height:17%;
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#00ffff', endColorstr='#0000ff');
}
#ie-5 {
    height:16%;
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#0000ff', endColorstr='#ff00ff');
}
#ie-6 {
    height:17%;
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ff00ff', endColorstr='#ff0000');
}

Not exactly pretty, but it is one way to get multiple color stops in Internet Explorer working.
