try
a.no-decor{
color:inherit;
//color:expression(this.parentNode.currentStyle['color']);
text-decoration:none;
}
That'll get rid of your blue color and the underline. You could use a similar expression for the underline, but you'd be better off just using text-decoration:none since that's all an inherited text-decoration is gonna give you anyhow and no need to use expressions when not absolutely necessary (you'll take a performance hit when using expressions).
