You didn't succeed because of following reasons:
- You didn't include the jQuery in your example file.
- You have a class called quick-links-containerin your HTML but in your JS you are using#quick-links-containerwhich returns an ID. So that needs to be changed to '.quick-links-container'
- You are using only show()on click therefore on click the div will always be set to show, instead you can usetoggle()to toggle the visibility of the div.
So, your javascript code needs to be modified to following:
$('.quicklinks-button').click(function(){ $('.quick-links-container').toggle();});
