Changing a style with Javascript

How do you change the background color of a specific style in a stylesheet? I have a style named "navH" and when the user clicks a link the style changes so all the objects on the page that have that style assigned change. How can I do this?

Take a look at these examples:

If so, the Tutorial is here:

No that's not really what I need. I'm looking for something more like this:

function changeColors(color) {
document.all.navH.background-color=color
}

Something like that. It will change the style and therefore all the elements with that class.

document.all.### refers to an ID.
A CSS class is not an ID.

So what should I use?

You can change specific attributes of a declared style class on your page, but it's not as easy as changing the class of individual elements. Here's a hint:
