How to put controls within different content placeholder without using form

Situation: I have a master page which has 3 content place holder but no form runat server.
In my Login.aspx I try to fill those place holders but it does't allow me without form runat server tag and once I add more than one form again it shows me :"A page can have only one server-side Form tag."

here is my code :

<%@ Page Title="" Language="C#" MasterPageFile="~/Site1.Master" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="DWDS_Lotus_Care_Final.Page" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder2" runat="server">
<form id="formUser" runat="server">
<p>
<asp:Label ID="lblUsername" runat="server" Text="Username"></asp:Label>
<asp:Button ID="btnLogout" runat="server" Text="Logout" />
</p>
</form>
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<form id="form1" runat="server">
<table style="width: 100%">
<tr>
<td style="width: 93px">
UserName :
</td>
<td style="width: 139px">
<asp:TextBox ID="txtUserName" runat="server"></asp:TextBox>
</td>
<td style="width: 307px">
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" ControlToValidate="txtUserName" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td style="width: 93px">
Password :</td>
<td style="width: 139px">
<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
</td>
<td style="width: 307px">
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" ControlToValidate="txtPassword" runat="server" ErrorMessage="*"></asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td style="width: 93px">
&nbsp;</td>
<td style="width: 139px">
<asp:Button ID="btnSubmit" Text="Submit" runat="server"
onclick="btnSubmit_Click" />
&nbsp;&nbsp;
<asp:Button ID="btnClear" Text="Clear" runat="server"
onclick="btnClear_Click" />
</td>
<td style="width: 307px">
<asp:LinkButton ID="linkRegister" Text="Register" runat="server"></asp:LinkButton>
</td>
</tr>
</table>
