Hey, I must be missing something obvious, but can someone explain what I'm doing wrong with my CSS? I would like all buttons to have a certain format, except a few. I was expecting to use CssClass in order to override the few that should be different, but they all seem to use the standard one.

My CSS:

        .btn
        {

             border:none;
             background-color:red;

        }


        input[type="submit"]
        {
             border: 2px solid black;
             background-color:green;

        }

All the buttons take the second value (green background, with a border). However, I have this button:

<asp:Button ID="btnAdd" CssClass="btn" runat="server" Text="Add" />

I was expecting this to have no border, and a red background, but it's the same as every other button.

Any ideas what I'm doing wrong? Thanks
