CSS1 Support - Nutscrape

[edgedesigns]

According to the CSS1 Support Charts, netscape SHOULD understand the following CSS code, but it doesn't. (netscape7.1)

.imgplacebtm {
background-attachment: fixed;
background-repeat: no-repeat;
background-position: center top;
}

Would you please test that and tell me whats up?

muchismo gracias!

Well, i've found out its the background-attachment: fixed; line that causes netscape to freak. IE handles it fine.

.imgplacebtm {
background-repeat: no-repeat;
background-position: center top;
}

This code works.

Anyone wanna chime in with some almighty powerful wisdom to enlighten me as to why?
