linking jquery in html
In this case, your test.js will not run, because you're loading it before jQuery. put it after jQuery:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script><script src="http://code.jquery.com/ui/1.9.2/jquery-ui.js"></script><script type="text/javascript" src="test.js"></script>
Add your test.js file after the jQuery libraries. This way your test.js file can use the libraries.
Seeing the answers I have nothing else to add but one more thing:
in your test.html file you have written
link rel="stylesheet" type="css/text" href="test.css"/
see where you have written
type="css/text"
there you need to change into
type="text/css"
so it will look like that
link rel="stylesheet" type="text/css" href="test.css"/
and in this case the CSS file will be linked to HTML file
