Listing 3: Manage.aspx

<%@ Page Language="VB" MasterPageFile="~/Default.master" 
    AutoEventWireup="false" CodeFile="Manage.aspx.vb" Inherits="Manage" 
    title="Manage Your Personal Web Site" %>

<asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server">

   <div class="shim column"></div>

   <div class="page" id="admin-albums">

      <div id="sidebar">
          <h3>Choose an area to manage</h3>
      </div>

      <div id="content">
          <table width="90%"><tr>
             <td><asp:ImageButton ID="ImageButton1" runat="server" 
                  ImageUrl="../Images/button_sitecontent.gif" 
                  PostBackUrl="Content.aspx" /></td>
             <td><asp:ImageButton ID="ImageButton2" runat="server" 
                  ImageUrl="../Images/button_manageusers.gif"  
                  PostBackUrl="Users.aspx" /></td>
             <td><asp:ImageButton ID="ImageButton3" runat="server" 
                  ImageUrl="../Images/button_albums.gif"  
                  PostBackUrl="Albums.aspx" /></td>
            </tr></table>
      </div>
      
   </div>
</asp:Content>

"Since this is a content page, you can see that it points to the master page to use the @Page directive's MasterPageFile attribute. Also, this page is rather simple. It uses the same CSS classes as the Albums.aspx page found in the Admin folder and simply contains a table holding three image buttons that each point to a different administration page. Running this page in the browser produces the graphic shown here in Figure 4."

I don't understand "It uses the same CSS classes as the Albums.aspx page found in the Admin folder". I just insert a table with 3 columns 1 row and put 3 imangebuttons inside. My code like this,

<%@ Page Language="C#" MasterPageFile="~/Default.master" Title="Manage Your Personal Web Site" Inherits="Manage" %>

<asp:Content ID="Content1" ContentPlaceHolderID="Main" Runat="Server">
    &nbsp;<table>
        <tr>
            <td style="width: 100px">
                <asp:ImageButton ID="ImageButton1" runat="server" AlternateText="Site Content" ImageUrl="~/Images/placeholder-100.jpg" PostBackUrl="Admin/Content.aspx" /></td>
            <td style="width: 100px">
                <asp:ImageButton ID="ImageButton2" runat="server" AlternateText="Manage Users" ImageUrl="~/Images/placeholder-100.jpg" PostBackUrl="Admin/Users.aspx" /></td>
            <td style="width: 100px">
                <asp:ImageButton ID="ImageButton3" runat="server" AlternateText="Albums" ImageUrl="~/Images/placeholder-100.jpg" PostBackUrl="Albums.aspx" /></td>
        </tr>
    </table>
</asp:Content>

I don't know how to get following code from IDE
<div class="shim column"></div>

   <div class="page" id="admin-albums">

      <div id="sidebar">
          <h3>Choose an area to manage</h3>
      </div>

I know the same question is how to bring me to "uses the same CSS classes as the Albums.aspx page found in the Admin folder".

Thank you a lot.
