ReferenceError: Can't find variable: $

Okay so I just began working on jQuery today, trying to implement a div sliding down. However, none of my jQuery is working, so I began with something simple (an alert). This still isn't working, and while browsing forums I found that I can use my browser (Safari) for debugging. While using this, it found an error in my javascript code: ReferenceError: Can't find variable: $

My coding:

<script type="text/javascript" src="script.js">

On my main page, and in my script.js:

$("#title").click(function () {

My FULL coding can be found here:
When clicking on the error, it highlights the ' $(document).ready(function() {' line.

I have tried other posts, but those errors had to do for example with Mobile devices.
Any help would be greatly appreciated, as I mentioned before I am a beginner with jQuery.

Extra Information: Browser Safari v.7.0.1 (the newest).

You have to import jQuery before using it:

<script src="//"></script>
<script type="text/javascript" src="script.js"></script>

Notice it is using // as protocol (not http:// or https://), it means: if your .html file is at a http:// server, it will get jQuery from, and if it is at a https:// server, it will get it from

Note: If, while developing, you open your HTML file in your browser instead of in a server, you should specify the protocol, as in this answer, otherwise it won't work:

<script src=""></script>

Also, you should, if possible, place your .js files at the bottom of the page, right before closing </body>. See more in here.
