I'm using Google Chrome.
Using Twitter Bootstrap, I want to add a simple alert, unfortunately the alert is not dismissing when the x is pressed!
Here's my code based on alert documentation:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
<!-- Bootstrap -->
<link href="css/bootstrap.min.css" rel="stylesheet" media="screen">
</head>
<body>
<div class="alert">
<button type="button" class="close" data-dismiss="alert">×</button>
<strong>Warning!</strong> Best check yo self, you're not looking too good.
</div>
</body>
</html>
And I also tried:
<!DOCTYPE html>
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js" type="text/javascript"></script>
<!-- Bootstrap -->
<link href="css/bootstrap.min.css" rel="stylesheet" media="screen">
</head>
<body>
<div class="alert">
<a href="#" class="close" data-dismiss="alert">×</a>
<strong>Warning!</strong> Best check yo self, you're not looking too good.
</div>
</body>
</html>
What is missing to make it dismiss ?

Thanks to davidkonrad's comment.
The solution is trivial, by adding:
<script src="js/bootstrap.min.js"></script>
I've written a small, customisable, jquery plugin that injects a properly formed Bootstrap 3 alert (with or without close button as you need it) with a minimum of fuss and allows you to easily regenerate it after the box is closed.
See https://github.com/davesag/jquery-bs3Alert for usage, tests, and examples.
