problem with html editor

I used Html Editor with firefox on my pc. I switched pcs and I tested my site again.. The HTML editor appears completely messed up across browsers ..It doesnt even look as good as it is on the original pc i deployed it. The question is why? And should I use ajax at all instead of jquery?

All the pages markup:

<%@ Page Title="" Language="C#" MasterPageFile="~/YourGuruMaster.master" AutoEventWireup="true" CodeFile="PostEdit.aspx.cs" Inherits="PostEdit" %>

<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit.HTMLEditor" tagprefix="cc1" %>

<asp:PlaceHolder ID="PlaceHolder1" runat="server"></asp:PlaceHolder>
<asp:PlaceHolder ID="PlaceHolder2" runat="server"></asp:PlaceHolder>

    <cc1:Editor 
        ID="Editor1" 
        Width="850px"  
        Height="400px"
        runat="server"/>
    <br />
    <asp:Button
        id="btnSubmit"
        Text="Submit"
        Run开发者_Go百科at="server" onclick="btnSubmit_Click" />






<br />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
    ControlToValidate="Editor1" ErrorMessage="אין להשאיר שדות רקים" 
    ForeColor="#CC0000"></asp:RequiredFieldValidator>

1.) This is a much deeper problem. You probably need to add more rules to your css stylesheet. If you want the site to look the same across different browsers, you have to look into cross browser support and cross browser compatibility.

2.) The jQuery library has a full suite of AJAX capabilities. There is no need to use self-made js functions to create AJAX calls. Stick with jQuery.
