Can screen readers be told to ignore certain text?

[NogDog]

I was thinking of using a CSS technique to create a drop shadow effect on some titles. This would result in the html having what amounts to duplicate text:

<h1 class=shadow>Some Title</h1>
<h1 class=top>Some Title</1>

So what I'm wondering is, is there some technique via CSS or HTML to tell accessibilty tools like text-to-speach readers or such to ignore certain text (in this case, ignore the <h1 class=shadow>Some Title</h1> line)?

It's not 100%, but for CSS2 browsers you can specify medium specific styles. Set that element's "display" to "none" but not for the screen.

There's a drop shadow style definition for text isn't there? It just isn't supported by browsers yet. I'm sure there is.

There sure is, and the only browser that supports it is, of course, IE.
