I am making a kind of gallery using the colorbox plugin (http://www.jacklmoore.com/colorbox/), and I somehow cannot get it to work.
I copied the demo code right off the webpage (I modified it to fit my links)
<link rel="stylesheet" href="colorbox.css" />
<a class='gallery' href='image.jpg'>Photo_1</a>
alert('colorbox is about to open')
You should get used to using either Firebug (a plugin for Firefox) and/or Google Chrome's inspector (which is there by default on Chrome). If you're using any of those, you can right click->inspect element, and then hit the 'Network' tab.
