What’s in an SPA?

Initially nothing. You can start from zero. Or have a landing page with a login, like in this case: <body> <div data-role="page" id="login"> <div class="login">         <label for="user">User</label><input id="user"/>               <label for="pwd">Password</label><input id="pwd" type="password" />    <button>Login</button>     </div> </div> </body>
