Declaring CSS and JS

Declaring CSS and JS

Is this a proper way to declare my CSS and JS?  Am I missing something?

<link rel="stylesheet" href="_jquery/jquery.mobile.theme-1.2.0.min.css">
<link rel="stylesheet" href="_jquery/jquery.mobile.structure-1.2.0.min.css">
<link rel="stylesheet" href="_jquery/jquery.mobile-1.2.0.min.css">
<link rel="stylesheet" href="_css/main.css">

<script src="_jquery/jquery-1.8.2.min.js"></script>
<script src="_jquery/jquery.mobile-1.2.0.min.js"></script>
<script src="_jquery/cordova-2.2.0.js"></script>


Thanks.
