Setting transparent background for DynamicMenuStyle Menu

[rh]

Hi,

I am using a ASP.NET 2.0 Menu control and would like the dynamic menu to
have a transparent background so that whatever is behind it is partly
visible between each dynamic menu item.

I've alredy tried the following but none of them worked:
1. Set DynamicMenuStyle.BackColor = Transparent
2. Set the DynamicMenuStyle.CssClass and specify "background-color:
Transparent;"
3. Set the DynamicMenuStyle.CssClass and specify "background-color:
url(../images/MyTransparentImage.gif);"

Any suggestions?
