Instead of using the error message "Error" I would like to change the textbox txtzipcode  background red using CSS can this be done.

<form id="form1" runat="server">
    <div>
   
        <asp:TextBox ID="txtzipcode" runat="server"></asp:TextBox>
        <asp:RegularExpressionValidator ID="ValZipcode" runat="server"
            BorderStyle="None" ControlToValidate="txtzipcode"
            ErrorMessage="Error"
           
           
            ValidationExpression="^((\d{5}-\d{4})|(\d{5})|([AaBbCcEeGgHhJjKkLlMmNnPpRrSsTtVvXxYy]\d[A-Za-z]\s?\d[A-Za-z]\d))$"
