Hi Guys,

I have created a Default.aspx page using HTML5 tags such as header, nav, section, footer.

1. The content renders fine on my dev machine (running IE11).

2. However, it doesn't render on my network (live client) PC running IE11. But, it is fine rendering in Chrome!!!!

Thoughts???

Here is an example:

Code:
<body>
    <form id="frmDefault" runat="server">
    <header>
        <h1>Resource Portal</h1>
    </header>
    <nav>
        <ajaxToolkit:ToolkitScriptManager ID="ToolkitScriptManager" runat="server" />
        <asp:UpdatePanel ID="UpdatePanelNav" runat="server">
        <ContentTemplate>
            <ajaxToolkit:RoundedCornersExtender TargetControlID="btn1" runat="server" Corners="TopLeft" Radius="20" />
            <ajaxToolkit:RoundedCornersExtender TargetControlID="2" runat="server" Corners="BottomRight" Radius="20" />
            <asp:Button CssClass="button" id="btn1" Text="xxxx" runat="server" />
            <asp:Button CssClass="button" id="btnX" Text="Ixxxx" runat="server" />
            <asp:Button CssClass="button" id="btnY" Text="xxx" runat="server" />
            <asp:Button CssClass="button" id="btn2" Text="xxxx" runat="server" />
            <%--Add New Buttons here (adjust RoundedCorners as required)--%>
        </ContentTemplate>
        </asp:UpdatePanel>
    </nav>
    <section>
	Bla, Bla, Bla
    </section>
    <footer>
         [Version 1.01]
    </footer>
    </form>
    </body>
