I'm trying to get an alert to disappear when the "x" button is clicked, but there seems to be something missing that's keeping it from working, not sure what it is.
<div class="alert alert-success alert-dismissible">
<button type = "button" class="close" data-dismiss = "alert">x</button>
You've done it!
</div>
for dismissible to work, you need to include jQuery and bootstrap.js in your document.
