asp.net buttons stopped working after I inked a StyleSheet

I've run into a problem while trying to style a content page. I created a content Page that have buttons in it and for some reason after I linked a styleSheet the buttons stopped working.
I would appreciate any help, thank u.
the content page:
<%# Page Title="" Language="C#" MasterPageFile="~/Pages/Site1.Master" AutoEventWireup="true" CodeBehind="MyBooks.aspx.cs" Inherits="WebApplication8.Pages.MyBooks" %>
<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">
<link href="../css/myBooks.css" rel="stylesheet" type="text/css" />
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
<div>
<asp:Button CssClass="addBook" ID="addBook" runat="server" Text="+Add book"
onclick="addBook_Click" />
<center><asp:DataList ID="DataList1" runat="server" Font-Bold="False"
Font-Italic="False" Font-Overline="False" Font-Strikeout="False"
Font-Underline="False" ForeColor="Gray">
<ItemTemplate>
<table class="style1">
<tr>
<td class="td">
<asp:Image CssClass="binding" ID="Image2" runat="server"
ImageUrl='<%# Bind("binding")%>'/>
<asp:Label ID="bookName" CssClass="bookName" runat="server" Text='<%# Bind("BookName") %>'></asp:Label>
</td>
<td>
<br />
<br />
<div class="buttons">
<asp:Button CssClass="btn1" ID="Publish" runat="server" Text="Publish" /><br />
<asp:Button CssClass="btn2" ID="Edit" runat="server" Text="Edit" /><br />
<asp:Button CssClass="btn2" ID="discared" runat="server" Text="discared" />
</div>
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList></center>
</div>
</asp:Content>
the styleSheet (linked in the first content place holder):
addBook is the cssClass of the first butoon in the content page
btn1 is the cssClass of the first button in the DataList.
btn2 is the cssClass of the tow other buttons below it.
buttons is the cssClass of the div who contains the three buttons inside the DataList.

You can set Ajax calendar extender for the textbox..
<asp:TextBox ID="dtpTransDate" runat="server" Width="90px"></asp:TextBox>
<asp:CalendarExtender ID="dtpTransDate_CalendarExtender" runat="server"
Enabled="True" Format="dd/MM/yyyy" TargetControlID="dtpTransDate">
</asp:CalendarExtender>

You can fix the issue with jQuery also.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script>
$(document).ready(function() {
$("#textboxid").datepicker();
});
</script>
<asp:TextBox ID="textboxid" runat="server" Width="100px"></asp:TextBox>
If the control is in a child page of a master page
then use ClientIDMode
<asp:TextBox ID="textboxid" runat="server" Width="100px" ClientIDMode="Static"></asp:TextBox>
Check below link for ClientIDMode
http://msdn.microsoft.com/en-us/library/system.web.ui.control.clientidmode(v=vs.110).aspx
For jQuery calender check below link
http://jqueryui.com/datepicker/

panel height not working in internet explorer 7

i have an ajax modalpopupextender that opens a popup in the event that an error occurs.
This works fine in all browsers i have tested so far. But not in internet explorer 7 (it does in ie 8 and 9)
basically the height of the panel isnt being applied. on screen its about 20 pixels high. I have no idea why and have used various samples to no avail for hours now. The width os working fine.
Any help appreciated
Thanks
