jquery in asp.net masterpage

Hi, I am using jquery in an asp.net form with a master page. Initially I could only get the jquery to work in a plain document not using a master page. But looking at the source when the page was running i noticed that where I had put the following source in the content section on the child page:

<input id="btnAnimate" type="button" value="Animate" />
        <asp:Panel ID="Panel1" runat="server">
        Some sample text in this panel        
        </asp:Panel>

it had changed the Panel id to
 <asp:Panel ID="ctl00_ContentPlaceHolder1_Panel1" runat="server">

so to get this to work I had to rename the object in the header content to reflect this.

<script type="text/javascript">
        $(document).ready(function() {
            $("#btnAnimate").click(function() {
            $("#ctl00_ContentPlaceHolder1_Panel1").animate(
            {
                width: "350px",
                opacity: 0.5,
                fontSize: "16px"
            }, 1800);
            });
        });
 </script>

My issue is why is this happening. As the ID is being changed dynamically when the page is run, how can I guarantee that the prefix placed will always be ctl00_ContentPlaceHolder1_ as I am not setting this. How does this get set and can I controll this. Also further issues arrise such as when using different browsers.

Many thanks in advance for any advice

Typical ASP issue

1. use classes instead OR
2. use $("<%= Panel1.ClientID %>").animate

So

<input id="btnAnimate" type="button" value="Animate" />
        <asp:Panel ID="Panel1" class="animatePanel" runat="server">
        Some sample text in this panel        
        </asp:Panel>

then have

<script type="text/javascript">
        $(document).ready(function() {
            $("#btnAnimate").click(function() {
            $(".animatePanel").animate(
            {
                width: "350px",
                opacity: 0.5,
                fontSize: "16px"
            }, 1800);
            });
        });
 </script>
