Why not putting all the form information in CSS only? If you setting the font in code behind (why?) why not setting the size as well?

There are many ways to do this..

1. Use Font-Size attribute

HTML

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Name cann't be blank" ControlToValidate="TextBox1" Font-Size="Small"></asp:RequiredFieldValidator>

or

HTML

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Name cann't be blank" ControlToValidate="TextBox1" Font-Size="11px"></asp:RequiredFieldValidator>

2. Use style property

XML

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Name cann't be blank" ControlToValidate="TextBox1" style="font-size:11px;"></asp:RequiredFieldValidator>

3. Through code behind.

C#

protected void Page_Load(object sender, EventArgs e)
    {
        if (!this.IsPostBack)
        {
            //RequiredFieldValidator1.Style.Add("font-size", "11px");
            //or
            RequiredFieldValidator1.CssClass = "err";
        }
    }

I think you missed to write your code in PageLoad event. check again.. hope this will help you..
