Not even particularly elegant code, for example, opacity is clamped between 0 and 1 in in the very next line a bounds check is made anyway. opacity = (opacity < 0) ? 0 : opacity;
opacity = (opacity > 1) ? 1 : opacity;
if(opacity >= 0 && opacity <= 1) {
document.getElementsByTagName("BODY")[0].style.opacity = opacity;
}
