specifying a proper path name for a plugin or a UI...

Ever since I started reading up about doing Plugins and UIs, I'm having some issues with my browsers apparently not accessing the ".css" & ".js" files as needed.

Here is some sample HTML code I made ...

<head>

  <meta charset="utf-8">
  <title>jQuery UI</title>
  <style type="text/css">
    .cool { width: 300px; height: 50px; border: 1px solid #000; }
.cooler { background-color: #CCC; border: 5px solid #444; width: 500px; height: 200px; }
  </style>
  <link rel="stylesheet" type="text/css" href="../jQuery User Interface/jquery-ui.min.css"
  <script src="../jQuery Scripts/jquery-1.11.1.min.js" type="text/javascript"></script>
  <script src="../jQuery User Interface/jquery-ui.min.js" type="text/javascript"></script>
  <script src="jqueryUIdemo.js" type="text/javascript"></script>
  
</head>

All I'm trying to do is ensure that this program is able to access both files (jquery-ui.min.css) & (jquery-ui.min.js). I simply downloaded the latest UI pkg from the site and unzipped it into the (./jQuery User Interface/) portion of my drive. Is there some issue with it not liking the way I set this up? 

My previous programs seem to run fine with this type of set up.

Any ideas?

Thanks!
