I am using Visual Studio 2008. My system dosen’t support element ‘nav’ when I writing asp.net code. Please help me?
My code :
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 5.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

</head>
<body>
<form id="form1" runat="server">

<nav class="navbar navbar-expand-lg navbar-light">
</div>
</nav>
</div>
</form>
</body>
</html>
